below are pictures of different applications of electromagnetic waves. state the type of electromagnetic wave used in each application

A cell phone is a radio transmitter and receiver that uses microwaves. Cellular phones depend on overlapping network of cells. Each cell has its tower that receives and sends microwave signals.

Ultraviolet (UV):

-Security Markings:

Sensitive documents such as credit cards, banknotes, and passports include a UV watermark that is only seen under UV emitting light.

Radio Waves:

-Radio/Television Signals:

Radio and Television signals are radio waves that are produced by making electrons vibrate. It has a long wavelength capable to transmit sound and picture information over long distances.

X-ray:

-Diagnosing Bone Fractures:

X-ray are produced using an X-ray tube. They are emitted when fast moving electrons hit a metal target. Long wavelength X-rays can penetrate the flesh but not the bones that's why it is used in diagnosing bone fractures.

Infrared:

-Thermal Imaging through Infrared Scanners:

Infrared scanner such as thermal imaging and thermal scanner are used to show the temperature variation of the body. Our body radiates infrared and under infrared cameras, our images appear in a variety of colors. The differences in color determine the differences in temperature. For example, shades of blue and green indicate regions of colder temperature; and red and yellow indicate warmer temperature.

-Night Vision Goggles:

Use thermal imaging technology to capture the infrared light being emitted as heat by objects in the field of view.
