Question

The refractive index of a prism for a monochromatic wave is square root 2 and its refractive index is 60 degree . For minimum deviations , the angle of incidence will be

Answer 1

A+dev.=2i

2i=60+sqrt2
i=(60+1.4)/2

i=30.7 degree

Assumption- angle of prism is 60 degree specified as r.i
