Questions
A prism is made up of a material of refractive index . The angle of the prism is . If the angle of minimum deviation is equal to the angle of the prism, then the value of A is :
detailed solution
Correct option is C
Given. μ=3,δm=Aμ=sin(A+δm2)sinA2or 3=sin(A+A2)sinA2=sinAsinA2=2sinA2cosA2sinA2=2cosA2∴ cosA2=32=cos300 or , A=600Talk to our academic expert!
