Power of a Lens - A Level Physics
Рет қаралды 8,885
6 жыл бұрынThis video introduces and explains the power of a lens for A Level Physics.
The more powerful a lens is, the more bending ability it has. The power of a lens is equal to the reciprocal of the focal length, P=1/f. The power of lenses is measured in dioptres, D.
Thanks for watching,

Uploading videos before school? You must have way better mornings than me, also great video on lenses. I'm in AS and it never made much sense last year.

What topic does lens come under in the current aqa spec?
@PhysicsOnline 6 жыл бұрын
It’s not on the spec for AQA, unless you do the optional topic about medical physics

Or the Astrophysics module.

i would rather watch 1 long fun 10 minute or even longer would be better, video and just like a lesson, with these short videos it would be better to make series and just call them chapter 1 and so on...

I have them arranged in a playlist and also on a page on my website too. Hopefully that makes it easier to find exactly the bits of information you really need. www.alevelphysicsonline.com/lenses
