Question

If angle of incidence on the mirror is 60° then angle of refraction will be​

Answer 1

Answer:

Explanation: it is also 60'

Because angle of incidence=angle of reflection

Answer 2

Answer:

This relationship between the angles of incidence and refraction and the indices of refraction of the two media is known as Snell's Law.

Snell's law :

$\boxed{n_{1}sin\theta_{1} = n_{2}sin\theta_{2}}$

Where,

n₁ =  incident index

n₂ = refracted index

θ₁ = incident angle

θ₂ = refracted angle

Angle of Incidence (degrees) Angle of Refraction (degrees)
