A beam of light is transmitted through a medium with an index of refraction of 1.46. What is the speed of the light beam as it travels through the medium?

The speed of light through the medium is 2.1 * 10^8 m/s

Step-by-step explanation:

In this question, we are asked to calculate the speed of light beam as it travels through a medium given the refractive index of the medium.

Mathematically;

n = c/v

where n is the refractive index, v is the speed of light through the medium and c is the speed of light in a vacuum.

From the question, we can identify that the refractive index is 1.46 and the speed of light through vacuum is 3 * 10^8 m/s

Rearranging the equation; we have;

v = c/n

v = (3 * 10^8)/1.46

v = 2.1 * 10^8 m/s

what are the answear choices to the question.
