Question

Light is considered which of the following?


a transverse wave


an electromagnetic wave


both a wave and a particle


all of the above

Answer 1

The Correct Answer: D

Light for certain covers a range of electromagnetic wavelengths. Electromagnetic waves are transverse waves which means its oscillation direction is perpendicular to its path. So both choices A and B are correct.
In choice C, as I said above it's clear that Light is a Wave. Light is made of Photons. Photons are fundamental particles which are well-explained in Particle Physics.

So all the choices above are correct.

Answer 2

All the Above
