Question
The cross-section of a prism is shown in the figure. One of its refracting surfaces AC is given by y = x2. A ray of light travelling parallel to x-axis is incident normally on face AB and refracted. The minimum distance of the incident ray from point A to get refracted ray from surface AC :-


Options
A.h = μ2
B.h = μ2/3
C.h = 
D.h = 
Solution
Sine of the angle of the incident ray with the normal to the curve should be less than 1/μ
