The angle of refraction of light ray in the corn oil is 20°.
What is angle of Refraction?
Angle of refraction is the angle the refracted light ray makes with the normal to the oil-air interface.
Given data:
Angle of incidence = 30°
Analysis:
The refractive index of oil is 1.47.
Using the formula for refractive index(n) = [tex]\frac{sini}{sinr}[/tex]
1.47 = [tex]\frac{sin 30}{sin r}[/tex]
1.47(sin r) = sin 30
sin r = [tex]\frac{sin 30}{1.47}[/tex]
sin r = 0.3401
r = arc sin(0.3401)
r = 19.88° which is approximately 20°
