The principal axis of a lens is the line along which light rays converge.
Light rays that pass through a lens converge at a point known as the focal point. The focal length of a lens is measured from the center of the lens to this point. The distance between the principal axis and the focal point is known as the optical axis, which is perpendicular to the principal axis. The principal axis lies in front of and behind a convex or concave lens, respectively.
What is an optical axix?
Light rays that pass through a convex or concave lens converge at a point known as the focal point. The distance between this focal point and where it intersects with an imaginary line drawn perpendicular to both sides of the lens (known as its principal axis) is known as its optical axis.

What has Tommy Dorfman been up to lately?
On October 26th 2018, Netflix released season 2 of their hit series 13 Reasons Why. In this season we saw some familiar faces return such as Dylan Minnette (Clay Jensen), Katherine Langford (Hannah Baker), Christian Navarro (Tony Padilla) and Alisha Boe (Jessica Davis). However one face that we were not expecting to see again was that of Ryan Shaver played by none other than Tommy Dorfman himself.
In episode 7 titled ‘There’s No Place Like Homecoming’, we see that after being suspended from school for smoking weed with Bryce Walker at prom night, Ryan is back at Liberty High School where he approaches Clay Jensen while he’s walking down the hallway after class one day.
“I’m sorry,” says Ryan apologetically.”I don’t want you mad at me.” Clay looks surprised by this apology but tells him “It’s okay” before walking away.
“It’s not okay,” says Ryan sadly.
“What do you want me to say?” asks Clay looking confused.
“I don’t know,” replies Ryan sadly.
“You can’t just apologize like that,” says Clay before adding “you have to explain why.”
“I’m sorry I left you alone with Bryce Walker,” says Ryan looking down ashamedly.”He drugged me.””Why didn’t you tell anyone?” asks Clay confused by this revelation.
“Because I thought I could handle it myself,” replies Ryan defensively.”And because I didn’t want everyone thinking I’m gay.””So why are you telling me now?” asks Clay.
Facebook shares dropped by more than 7% on October 26th, following the company’s announcement that it had been breached.
Facebook has suffered a major data breach that has affected 50 million users. The breach was discovered on Tuesday and was caused by a vulnerability in Facebook’s code that allowed hackers to take over user accounts. Facebook has since fixed the issue and is working with law enforcement to find out who is responsible for the attack. This isn’t the first time Facebook has been hacked, but it may be one of the most damaging incidents yet. Here’s why investors are so concerned about this breach.
What happened?
The hack occurred on Tuesday, October 25th when a security vulnerability in Facebook’s code allowed hackers to take over user accounts. The attackers were able to access users’ names, email addresses or phone numbers and potentially even their private messages and posts.
How many people were affected?
The company announced on Friday that 50 million users had been affected by the hack, which is more than twice as many as originally thought.
“This is an issue of trust,” said David Kirkpatrick, author of “The Facebook Effect.” “It’s not just people’s information they’re taking; it’s their identity.”
The fact that pure acetic acid does not turn blue litmus to red is a common chemistry experiment.
One of the most common chemistry experiments students perform in high school involves mixing a solution of blue litmus with a solution of pure acetic acid. When this happens, the mixture turns red, but if there is any water present in the mixture, it will turn blue instead. This is because acetic acid reacts with water to form acetic acid and hydrogen ions. The reaction that takes place between litmus and acetic acid is the same one that takes place between an acidic solution and a base solution, which causes both solutions to change color.
However, when pure acetic acid is mixed with water, no reaction occurs. This means that there are no hydrogen ions present for the two solutions to react with each other. The lack of hydrogen ions also means that there are no protons present for the two solutions to react with each other either. As such, no reaction occurs between pure acetic acid and water.

The UK’s energy prices have risen over the past year, despite the government’s attempts to help.
As of October 27th, 2022, the UK’s energy prices have risen by 2.7%. This is a huge increase from the previous year, when prices rose by just 0.4%. The reason for this increase is because of an increase in wholesale gas and electricity costs. These are costs that are passed on to consumers and make up about half of their bills.
While wholesale costs are rising, it is still unclear why they are rising so much more than expected. One reason could be that there is less gas being produced in the UK. According to data from Oil & Gas UK, only 10% of natural gas was produced in Britain in 2017/18 compared to 28% in 2010/11.
Another reason could be that renewable energy sources such as wind and solar power are getting more popular with customers. These renewable sources don’t produce enough energy to meet customer demand at all times, so traditional power plants need to be used more often. This means that traditional power plants can charge higher rates for their services.
Black History Month is celebrated in February because it marks the birthdays of both Abraham Lincoln and Frederick Douglass.
February is Black History Month, a time to celebrate the achievements of black people throughout history. It’s also a time to reflect on how black people have been treated by white society over the years. The month is celebrated in February because it marks the birthdays of both Abraham Lincoln and Frederick Douglass, two men who had a profound impact on American history.
Why is Black History Month in February?
Abraham Lincoln was born on February 12th 1809, while Frederick Douglass was born 200 years ago today, on February 14th 1818. This made them two of the most influential figures in African-American history and their respective birthdays were chosen as the focal points for Black History Month celebrations.
Whoopi Goldberg had a very public spat with fellow co-host Joy Behar, but it seems the two have made up.
On Monday, October 22nd, Whoopi Goldberg hosted the show for the first time since she and Joy Behar had a very public spat. The two hosts had been going back and forth on social media for weeks over differing opinions on how to deal with Donald Trump’s presidency. The feud between the two co-hosts came to a head when Whoopi accused Joy of “carrying water” for Trump by not supporting his impeachment. When the two hosts appeared together on air after their Twitter feud, it was clear that there was still tension between them. However, this week both women seemed much more relaxed in each other’s company.
On Monday morning’s episode of The View, Joy joked about her and Whoopi’s feud while introducing some new segments on the show. “You know what? I just want to say something real quick before we get started because I know there are people out there who are concerned about our relationship and I want you to know that we are fine,” she said. “We really are fine.” She then went on to introduce some new segments including “Which One Are You?” where they would ask viewers which one of them they were more like.
There were no Rangers fans at Celtic Park for the first time in almost 50 years.
There were no Rangers fans at Celtic Park for the first time in almost 50 years. The last time there was no Rangers fans present at a Celtic match was on January 15, 1972, when the two sides met in a cup game. However, it’s not like there weren’t any fans from Glasgow at all. There were plenty of Celtic supporters from other parts of Scotland and England.
The reason for this was that it was felt that travelling to Glasgow would be too dangerous for many Rangers fans. The club released a statement prior to the match saying that they had received information that some Rangers supporters would be attacked by their own kind if they travelled to Glasgow.
Rangers have had issues with their own fan base this season and have been forced to play matches behind closed doors due to crowd trouble. This meant that they could not bring away supporters with them and as such decided against allowing them to travel.
