You should include some kind of control for aperture as well, to show WHY squinting tends to improve focus (at the expense of brightness) like a pinhole camera.

Nice! Useful for physics classes.

Where was this video in highschool

[@KarlFFF]

Can a dial be added to play with the curvature of the lens also?

[@ihormatkivskyy7023]

You should make a mobile app

[@CamStudiosFilms]

Good channel though you need more videos

When I move the object between the focus and the pole it shows no image...... at-least show the magnified image and say that it is virtual.....

[@Hampardo]

Not working for me. I'm unable to move anything, or press any button aside from the comments tab. Exactly the same happens in the laser one. Using W7/Chrome, with updated browser, Flash & Java.

A few other people have had problems too. Difficult for me to replicate. Trying to track it down. Thanks!

[@MrNoScoper1999]

***** I am having the same problem. I am also using windows7

[@ninjablox7264]

Hmm weird. I use an ipad and it is working.

These will be so usefull in my next internship! (studying for teacher highschool physics)

[@MichaelPomeroyinmauritania]

get a degree in physics instead of education. Every highschool teacher ive ever met who had a degree in ed was a joke. see math teachers should be experts in math and physics teachers should be experts in physics and biology teachers should be experts in biology. a degree in Education is a degree in babysitting.

[@Soldier842]

Michael Pomeroy Why is a teacher without a degree in physics a joke? Especially for youngsters (age 12-15/16) the level of physics I'm taught is well above anything they need to know. I think any teacher has to have a certain passion for the "babysitting" part of teaching in order to be a good teacher. (at the age 12-18/19 that is; teaching adults is diffrent) EDIT: 1 note, Im living in the Netherlands. The whole system of education might be diffrent (better? I don't know... it has it's flaws) than where you live.

[@MichaelPomeroyinmauritania]

Victor G a physics teacher without a degree in physics is a joke. maybe you should re-read my post....can you tell me what you ment by the word "Need" in this sentence you wrote?....."the level of physics I'm taught is well above anything they need to know."

[@MichaelPomeroyinmauritania]

***** When I got into highschool I had a curiosity about science and math. from 8th grade on, not a single teacher could give me real answers about my math and science questions. I wondered why and then I found out none of them had degrees in the subjects they taught. It was like someone was teaching us by reading the lesson from the book the night before. Pathetic!!!

[@PeterGeras]

By the end of high school when I could answer math questions that my math teachers can't, well that's just embarrassing...

[@sandeepkasuganti2585]

i also found a trick.,just close one eye and shorten the other eye .,now look at the target .,you will definately have a clear vision.,I BET U ON THIS STUFF
