A piece of glass shaped as shown, with a refractive index
of 1.5 allows light to pass through it striking point B. In
order to make the light strike point A, the piece of glass
should be:
*(light source)
................ (lens)
* *
point A point B
A. raised.
B. lowered.
C. made thicker from top to holtom.
D. made thinner from top to bottom.
Could anybody explain how to tackle this question? thanks a lot.
