Question

Light waves A) do not require a medium. B) can not travel in a vacuum. C) are not electromagnetic radiation. D) do not travel in straight lines from the source.

Answer 1

Light waves a) do not require a medium

Answer 2

Light waves A) do not require a medium.

Step-by-step explanation:

Light waves are electromagnetic waves. The electric and magnetic field lines vibrate perpendicular to each other. The wave carries energy in direction perpendicular to both electric and magnetic field. Light waves can travel in vacuum. These rays travel in straight lines in all the direction from point source.

Thus, option A is correct.
