Question

how can you explain the change in the size of lemon when it let in glass tumbler?​

Answer 1

Explanation:

Since water is more optically dense than air so light would bend towards the normal. Due to this different light rays meet above the actual position of the lemon. This refraction causes the bending of rays and results in the diverging image. Therefore the lemon appearsto be raised and slightly bigger.
