Answer:
The reflected angle is 20 °.
The angle of refraction = 12.34°.
Explanation:
For reflection,
Angle of incidence = Angle of the reflection.
Thus,
Given that the angle of incidence is 20 °
So, the reflected angle is 20°.
For refraction,
Using Snell's law as:
Where,
Θ₁ is the angle of incidence
Θ₂ is the angle of refraction
n₁ is the refractive index of water which is 1
n₂ is the refractive index of water which is 1.6
So,
Angle of refraction = sin⁻¹ 0.56 = 12.34°.
