Question

Which waves of the sun are perceived by the skin as heat

Answer 1

Infrared rays of the sun are perceived by the skin as heat.

• The solar radiation brings three main types of rays to our planet -

1) UV rays.

2) Infrared rays.

3) Visible light rays.

• Now,UV rays are mostly blocked before reaching to us because it is harmful.

• And, visible light rays don't have any kind of heating capabilities.

• So, it's obvious that the heat coming from the sun is the infrared rays of the solar radiation which is also absorbed by our skin.

Answer 2

Infrared rays are perceived as heat rays by the skin.

Explanation:

• Infrared rays are perceived as heat rays by the skin.
• Infrared rays are electromagnetic radiations and the rays coming from the sun are infrared radiations.
• The wavelength of infrared radiation is longer than the visible rays.
• Their range is from 400-700 nm.
• Thus these rays are invisible and can not be seen by the naked human eye but we feel them as heat.
