Answer 1

Answer:

Four properties of ultraviolet radiation are

• They are invisible to human beings
• It has shorter wave lengths than visible light.
• It is a type of electromagnetic radiation
• They have wavelength from 10nm to 400nm

Four properties of Infrared radiation are

• It has longer wave than visible light.
• They are heating rays emitted by high temperature bodies
• They can't be seen with a naked eye
• They can pass through dense region of gas and dust in space

Answer 2

Answer:

hey mate

Explanation:

here is your answer

(i) properties of ultraviolet radiation:

1. They are not penetrating even at high energies
2. They affect photographic plates
3. They cause photoelectric effect
4. they induce production of vitamin D in the skin

(ii) production of infrared radiation:

1. They affect photographic plates
2. They can pass through thick fog and mist and dense regions of interstellar GA dust.
3. Near-IR radiation wavelength up to a few micrometers can pass through glass. Far-ID radiation is strongly absorbed by glass
4. They can be easily reflected and retracted
