Homework Statement
Light of wavelength 612nm in a vacuum travels 1.57pm in a medium of index of refraction 1.51. Find
a)The wavelength in the medium.
b)the optical path length
c)the phase difference after moving that distance, with respect to light traveling the same distance in vacuum.
Homework Equations
The optical path length L=n1L1 + n2L2
The Attempt at a Solution
I got A but I can't figure out B and C. I think it is because I don't really picture the situation.
