Question

(b) Determine the value of the angle of incident for a ray of light
travelling from a medium of refractive index ui = 2 into the medium
of refractive index H2 = 1, so that it just grazed along the surface of
separation.
​

Answer 1

Answer:

• Determine the value of the angle of incidence for a ray of light travelling from a medium of refractive index μ1=2 into the medium of refractive index μ2=1, so that it just grazes along the surface of separation.
