Expert Answer:

Here angle of incidence is 45degree

refractive index = 1.6

angle of refraction =?

we know that  n = sin i / sin r

or                      1.6 = sin45ο /sin r = .7071/ sinr

or                     sin r = .7071 / 1.6

  or                       r = 26.2ο

thus angle of refraction  = 26.2ο
