Aray of light strikes a flat block of glass (n = 1.52) of thickness 1.50 cm at an angle of 36.0° with the normal. trace the light beam through the glass, and find the angles of incidence and refraction at each surface. if the angle of incidence at first surface is 36.0° (all angles are measured from the normal), determine the following angles. angle of refraction at first surface

angle of refraction at first surface is 22.74°

Step-by-step explanation:

Given data

thickness = 1.50 cm

n = 1.52

angle = 36.0°

to find out

angle of refraction at first surface

solution

we will apply here  Snells law that is

n1 sinθ1 = n2 sinθ2

θ2 = sin^-1 ( n1/n2) sin θ1

here n1 is 1 and n2 is 1.52 and θ1 = 36.0°

θ2 = sin^-1 ( n1/n2) sin θ1

θ2 = sin^-1 ( 1 / 1.52 ) sin36

θ2 = 22.74°

angle of refraction at first surface is 22.74°
