*** WHAT'S COVERED ***
1. The two main types of lenses and how they refract light
physics paper lock in gng
* Convex (converging) lenses that focus parallel light rays to a principal focus.
* Concave (diverging) lenses that disperse parallel light rays.
gcse physics paper 2 tmr guys, lock in
2. Key properties and terminology for lenses
* The principal focus (or focal point) and the axis of a lens.
* The definition of focal length.
* The relationship between focal length, lens curvature, and the power of a lens.
great, thanks. best video on this I have seen
3. The difference between real and virtual images
* How real images are formed when light rays actually converge.
oh cog i love you sm
* How virtual images are formed where light rays only appear to converge.
4. How to describe the properties of an image
I appreciate how he basically explains without beating around the bush, this video strengthened my basics alot :D keep it up champ!
* Identifying if an image is real or virtual.
* Determining if an image is upright or inverted.
why are they both smaller
* Comparing the size of the image to the object (magnification).

AQA - Separate science only
IGCSE Edexcel - Not in your course
Was so glad to find out you had this topic explained. Personally i find your style of teaching the most clear and straight to the point. Please post more, much love dude
Edexcel - Separate science only
OCR 21st Century - Separate science only
One of the most unfair and worst video I’ve seen from you beast. No hate to you but just don’t make these kind of videos anywhere it was better when you made videos more like challenges compared to these tv shows ahh videos. Anyways no hate to you just don’t like these type of videos which aren’t really nice to watch when eating breakfast!!!❤

Cognito is my life saver. I had a big public exam last year - aced it bcoz of this channel! I really wish they upload more videos for KS3 bio, chem and phy

How tf r yall posting before it got out
@qaisghassan4231Only reason I understand
@Ebrahim-d7r9dGUYS COGNITO JS POSTED!! honestly i think cognito is the sole reason i'm passing my gcses
