Hi, I have a question and I hope anyone could answer it:
A person got his eyes tested by an optician. The prescription for the spectacle lenses to be made reads:
Left eye : + 2.50 D ; Right eye : + 2.00 D
(a) State whether these lenses are thicker in the middle or at the edges.
(b) Which lens bends the light rays more strongly?
(c) State whether these spectacles lenses will converge light rays or diverge light rays.
