Yaritza Friedman · Answer 1

Microwaves

Infrared Waves

Visible Light

Explanation:

Electromagnetic waves consist of oscillating electric and magnetic field, which vibrate in a direction perpendicular to the direction of motion of the wave (for this reason, they are called transverse waves).

Electromagnetic waves are the only waves that do not need a medium to propagate: in fact, they can travel through a vacuum as well.

Electromagnetic waves are classified into 7 different types depending on their frequency. From highest to lowest frequency, they are:

Gamma rays

X-rays

Ultraviolet

Visible light

Infrared Waves

Microwaves

Radio waves

All the other options are a different type of waves, called 'mechanical waves', therefore they are not electromagnetic waves.
