Waves Study Guide

Front

What are electromagnetic (EM) waves?

Back

Electromagnetic waves are waves that can travel through space and do not require a medium. They include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

What type of waves from the sun can cause sunburn?

Back

Ultraviolet waves from the sun can cause sunburn.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's travel, such as sound waves.

What is the difference between a transverse wave and a longitudinal wave?

Back

In a transverse wave, the particles move perpendicular to the direction of the wave, while in a longitudinal wave, the particles move parallel to the direction of the wave.
