The angle of refraction of the light beam is determined as 16.46 ⁰.
n = sin i / sin r
where;'
Angle between the ray and the normal = incident angle = 24.8⁰
1.48 = sin (24.8) / (sin r)
sin r = sin (24.8) / (1.48)
sin r = 0.283
r = sin ⁻¹(0.283)
r = 16.46 ⁰
Thus, the angle of refraction of the light beam is determined as 16.46 ⁰.
