If you look through a glass magnifying glass under water, as opposed to in air, the magnification decreases. Can someone explain to me why?
I thought it would be opposite. Since the index of refraction is more for water, the angle of refraction would be greater in water (as opposed to air). Since the angel of refraction is greater, the image height will be greater (relative to the normal). Since the height of the image will be greater in water, shouldn't the magnification increase?
(This is a question from EK Physics, page 151, question 179)
