Question

Which radiation in sunlight, causes a heating effect?

Answer 1

Heating effect on the earth

• Sunlight is a mixture of infrared and ultraviolet radiation that comes from the sun.
• These rays are electromagnetic radiations.
• When the earth's surface receives incoming solar energy, it heats up.
• Some of the radiation is reflected back into the atmosphere and clouds by the atmosphere and clouds.
• When matter absorbs energy, it causes the materials to heat up.

Infrared radiation

• The warming of the earth's surface is due to infrared radiation.
• Due to its longer wavelengths, infrared radiation is reflected more than ultraviolet or visible radiation.
• The heating effect is caused by infrared radiation transferring heat between the surface, water, and air.
