AQA Unit 3- Mirrors & Lenses

Showing 1 to 5 of 5

This is topic that I find really hard. I find it hard to see the difference between a convex and concave mirror and lens. If anyone can help me or attach some resources, please do so.

Convex belches outwards, like you eye.

I remember concave because the mirror caves into itself XD. I.e. it's like you breathing in, and your stomach goes in, if ya get meh :L

it is really confusing, a convex mirror (like Zak said) is outwards and diverges the rays (produces a virtual image), whereas a concave mirror is like a cave and converges the rays!

lens are different though, a convex lens converges the rays but a concave mirror diverges the rays!

it took me a while to understand them too. Just keep going over them and you'll do fine, good luck!x x
