Question

When the medium is uniform, how do light waves travel through it?\

A. Irregular motion

B. vibrating motion

C. circular motion

D. straight line motion

Answer 1

Your answer should be D. Straight line motion. Hope this helps! ;)

Answer 2

Answer: D. straight line motion

Explanation:

A wave travels in circular motion/irregular motion/vibrating motion when the medium is non-uniform or there is unbalanced force acting on it.

when the medium is uniform, the wave would continue to travel in the straight path and would not deviate. A light wave always moves in straight path in a given medium. It bends when the medium changes.
