Calculation of the Refractive Index of Glass

To find the refractive index of glass, we can use Snell's law, which relates the angles of incidence and refraction to the refractive indices of the two media involved.

Snell's law states:

n1 * sin(θ1) = n2 * sin(θ2)

Where: - n1 is the refractive index of the medium of incidence (in this case, air) - θ1 is the angle of incidence - n2 is the refractive index of the medium of refraction (in this case, glass) - θ2 is the angle of refraction

In this case, we are given that the angle of incidence (θ1) is 60 degrees and the angle of refraction (θ2) is 30 degrees.

Let's substitute these values into Snell's law and solve for the refractive index of glass (n2):

n1 * sin(θ1) = n2 * sin(θ2)

1 * sin(60) = n2 * sin(30)

Simplifying the equation:

sin(60) = n2 * sin(30)

Using the trigonometric values of sin(60) = √3/2 and sin(30) = 1/2:

(√3/2) = n2 * (1/2)

Simplifying further:

√3 = n2/2

Multiplying both sides by 2:

2√3 = n2

Therefore, the refractive index of glass is 2√3.
