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

Hello,

I believe you're asking which option is true. If so, A) do not require a medium. Unlike mechanical waves, electromagnetic (or light) waves do not require a medium. It has been proven that light travels in a straight line. Light waves are, in fact, electromagnetic radiation, and they can travel in a vacuum.
