1. The Problem(adsbygoogle = window.adsbygoogle || []).push({});

A thin beam of white light is directed at an angle α = 36.4° with respect to the horizontal, onto the top of a square block of silicate flint glass near its top corner. The perpendicular length of the block (or height is 1cm). The block’s refractive index n is 1.66 for blue light (λ0 = 400 nm) and 1.61 for red light (λ0 = 700 nm). The block is surrounded by vacuum.

Find the lateral displacement l between the two rays leaving the bottom surface of the block, as shown. (Note that l is measured perpendicularly to the rays.)

2.The relevant equation:

n1sin(theta1)=n2sin(theta2)

I do realize that I need use this formula twice

but I am not exactly sure what LATERAL DISPLACEMENT means :S

if someone can explain what is it I am supposed to find, I would appreciate it.

Hints are more than welcome.

Thanks
