Choose all of the following that are examples of electromagnetic radiation. sound waves ,microwaves, all of these, "the force", infared waves, water waves, visible light, none of these

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.

you would expect a sound wave to speed up. - b)
