Light from a laser pointer is goes through a window composed of crown glass, which has an index of refraction of 1.523. What is the speed of the light while it is in the window glass

1.97 * 10^8 m/s

Explanation:

Parameters given:

Refractive index, n = 1.523

Refractive index is the ratio of the speed of light in a vacuum to the speed of light in a specified medium.

When the medium is glass, the refractive index is given as:

n = Vv/Vg

Where Vv = velocity of light in a vacuum

Vg = velocity of light in glass

The velocity of light in a vacuum is 3 * 10^8 m/s. Therefore,

1.523 = (3 * 10^8)/Vg

Vg = (3 * 10^8)/1.523

Vg = 1.97 * 10^8 m/s

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
