​

Answer 1

Answer:

Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light. Light is made of waves of different frequencies.

Answer 2

Electromagnetic radiation transmits the heat from sun to earth.

Explanation:

• Sun is millions kilometers away from the Earth but electromagnetic radiation spectrum takes heat energy from sun and transfer heat energy to earth.

• There are many radiations in Electromagnetic radiation spectrum existing in different wavelength range which are Radio waves, Micro waves, IR rays, Visible light, Ultra violet, Gamma rays and X-rays.

• But We can't see these type of radiations that is they all are invisible to us, human beings, we can only see Visible light : the different seven colors (VIBGYOR) whose wavelength range is $400 - 700 nm.$
