5. What is refractive index of a refracting medium where the angle refraction is 45°for an angle of incidence of 30°​

Answer 1

Answer:

0.707

Explanation:

refractive index = sin (angle of incidence) / sin (angle of refraction)

                          =  sin30/sin45

                          =  (1/2) / (1/$\sqrt{2}$)

                           = 0.707
