Question

Which radiation in sunlight causes a heating effect?

Answer 1

Hint: The radiation which has a longer wavelength and can go deeply into objects to cause heating effects. . As the surface absorbs heat which comes from the sun, the surface becomes warmer than the surrounding atmosphere.

Complete step by step solution:
Infrared radiation in sunlight causes heating effects. Earth absorbs infrared radiation which then converts it into thermal energy the warmed air rises, cooler air sinks to the surface. The warm air which rises is called thermal. Earth starts heating when solar radiation falls on it. Solar radiation consists of visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Some radiation goes back into the atmosphere. Sunlight consists of infrared and ultraviolet waves. These rays are electromagnetic waves. Electromagnets are a type of magnet in which a magnetic field is produced by passing an electric current. Magnetism is created by electromagnets with the help of electricity. As the light turns on or off , electromagnets also turn on or off. Scrap metals are picked up by cranes which have electromagnets. High speed trains use strong magnets of high power known as maglev.
Infrared radiation is responsible for heating the earth 's surface. Sun causes heat by exciting electrons. Solar radiation is electromagnetic energy from the sun. It is responsible for light and heat for the Earth and energy which helps in the process of photosynthesis. We can’t see ultraviolet radiation. Heat and light are created by nuclear fusion. The greenhouse effect which has some strong effects like clouds which are present in the atmosphere reflects back a little sunlight before reaching to the ground which results in reduction of heat on the ground.

Note: Alpha rays are the weakest which are usually blocked by human skin and gamma rays are the strongest and only dense elements like lead can block them. Organisms living on earth get heat and light from the sun. If the sun is not present then earth will be dark and cold too. The thing which is very hot in the universe is supernova.
