what is infra red rays and U V rays give one example of each?

Answer 1

Hey mate

    here is your answer :))

***************************

Ultraviolet radiation

• Ultraviolet radiation. Invisible rays that are part of the energy that comes from the sun, can burn the skin, and cause skin cancer. UV radiation is made up of three types of rays -- ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC).

Infrared radiation

• Infrared radiation is a type of electromagnetic radiation, as are radio waves, ultraviolet radiation, X-rays and microwaves. Infrared (IR) light is the part of the EM spectrum that people encounter most in everyday life, although much of it goes unnoticed. It is invisible to human eyes, but people can feel it as heat.

$\Large\bold\star\underline{\underline\textbf{Ultra voilet rays\:}}$

→ The wavelength of UV rays varies from 400 nm to 0.6 nm. The welders wear special goggles with glass to protect the eyes from UV rays.

→ The sun is an important source of UV rays.

→ These waves are absorbed by the ozone layer in the atmosphere.

→ These rays are very harmful to living
tissues.

→ UV radiation is absorbed by ordinary glass

→ They are used to preserve food stuff and also tor the study of the structure of molecules.



» Example : UVA, UVB and UVC rays

$\Large\bold\star\underline{\underline\textbf{Infrared waves\:}}$

→ These waves have the wavelength range from 7x10 ^-7 m to 7x10^-4 m.

→ These waves are produced by the hot bodies and also known as the heat waves. Infrared lamps are used in physical therapy.

→ These rays from the sun keep the earth
warm. These rays are used in the remote switches of household systems.





» Example → Heat from an electrical heater or fire , Burning charcoal.
