What are examples of devices that use electromagnetic waves? check all that apply. fm radios microwaves tv remote controls alarm clocks x-rays

its FM radios microwaves TV remote controls and  X-rays

The correct answer are "FM radios and TV remote controls".

Explanation:

Electromagnetic wave is the wave in which both electric field and the magnetic field are mutually perpendicular to the direction of the motion of the wave.

Electromagnetic wave can travel in vacuum. It does not need any medium to travel. It travels with the speed of the light.

For example, X-rays, microwaves, infrared radiation etc.

In the given options of the problem, only FM radio uses electromagnetic wave while microwaves and X-rays are electromagnetic waves. Radio wave is electromagnetic wave. It is used in communication technologies such as radios, TV etc. In radio, it receives radio waves. Then, the radio waves get converted into mechanical vibrations in speaker to create sound waves.

Remote control is a wireless device. Remote control sends signal by using infrared radiation.

Alarm does not use electromagnetic wave.

Therefore, the correct options are FM radio and TV remote controls.
