Homework Statement
A light ray has an incident angle of 30 degrees onto the vertex of a +500D mirror in air (directly on the optical axis). By how many degrees is the light ray deviated from its original path?
Homework Equations
n (delta) = (n'-n) (alpha)
n'= [ n sin [(alpha + delta)/2] / [sin (alpha /2)]
alpha = i1' + i2
n sin i1 = n' sin i1'
n' sin i2 = n sin i2'
but the prism index is not given and the alpha angle is not given so I don't know how to approach this question.
The Attempt at a Solution
choices are:
a. 0 degree
b. 30 degrees
c. 60 degrees
d. 90 degrees
e. 120 degrees
