Q 3110767610.     (i) When white light passes through a prism, it undergoes dispersion .

Here violet, indigo and blue colors are more
deviated than green, yellow, orange and red
colours `( mu_(violet ) > mu_(red) )` .


When white light ray passes from denser
medium to rarer medium, and the angle of
incidence is equal to the critical angle for green
colour light, how does green light emerge out
of the interface separating the two media?

from `mu = 1/(sin C)`, find which colours will be

refracted and which colours will be reflected
into the same medium.

(ii) Red, orange and yellow pass into rarer medium;
blue, indigo and violet reflect back into denser
medium.
