When light passes through a lens, it bends—this is called refraction. It happens because light changes speed when moving between materials (like from air into glass or plastic).

That's so cool how light bends like that, really makes you appreciate everyday things more!

True 💯💯

Does this change in speed affect the time it would require to get to the end of its travel?

Does the type of lens material (like glass vs. plastic) make a big difference in how much the light bends?

It’s wild to think our vision depends on this bending of light—both in nature and in tech like cameras and glasses.
