Absolute hero. Thank you

[@thetheoryoflexism8903]

Understood the assignment. Clear and simple explantion. Thank you.

[@simranKaur-dm6tl]

Very clear explanation, thanks :)

[@yaavlogs4128]

do you have any experience with how to answer past papers questions? if so, i'm sure us students taking the exam this January will really benefit from your advice and explanations. Thank you and i really enjoy watching your videos!

Why do you draw a dotted line through the lens?

[@lovattphysics6366]

Penny Butter you can draw any kind of line through the lens. At GCSE you need to think about all the refraction from the lens happening at the centre of the lens - the line is there so you can tell exactly where that is! Hope that helps :)

I am still unable to understand diverging lens even after watching this video plzzzzzz help me

[@lovattphysics6366]

Academy Of everything OK, so you have parallel rays of light going into the lens from one side, lets say the left. The diverging lens bends them outwards, away from each other. So now you have two rays coming out of the right side of the lens getting further and further apart. Right? Well if they are getting further and further apart as they move to the right, then if you go far enough to the LEFT, then they would (if the lens wasn’t there) meet each other. This point where they would meet is where the image is formed. Of course, they don’t actually meet there because the lens IS there, so the image is a virtual image - not formed by real rays. Try drawing out the diagram using what I have written here - I hope that helps!
