Degrees, the angle of refraction is 30 degrees. The refractive index of water is 1.33. What is the refractive index of glass?

To solve this problem, we can use Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two media.

Given:
Angle of incidence (i) = 50 degrees
Angle of refraction (r) = 30 degrees
Refractive index of water (n1) = 1.33

We need to find the refractive index of glass (n2).

Using Snell's Law:
n1 * sin(i) = n2 * sin(r)

Plugging in the values:
1.33 * sin(50) = n2 * sin(30)

Let's calculate the values:

sin(50) ≈ 0.766
sin(30) = 0.5

1.33 * 0.766 = n2 * 0.5

n2 = (1.33 * 0.766) / 0.5
n2 ≈ 2.04

Therefore, the refractive index of glass is approximately 2.04.
