Homework Statement
Light traveling thorugh air is at incident at point x on the block of ice. If the refractive index is 1.3, calculate
a) the critical angle at the ice-air interface (3 marks)
b) the minimum angle of incidence, for the light to Y refracted out of the block at any point along the top surface (7 marks)
Homework Equations
The Attempt at a Solution
a) sin(θc)=1/nm
θ= sin-1(1/1.3)
θ= 50.3 (1 d.p)
is this right?
b) Need help on this one
