Question

The energy received by the Earth from the Sun is called as

• A. Electromagnetic radiation
• B. Gamma radiation
• C. X - ray radiation
• D. UV radiation

Hint:

The Sun emits energy across a wide range of wavelengths, from gamma rays and X-rays through ultraviolet, visible light, infrared and radio waves.

Answer 1

The Correct Option is A

Step 1: Understand what comes from the Sun.
The Sun is a hot ball of gas. Like any hot body, it gives out energy as waves. These waves do not need any material to travel through, so they can cross empty space and reach us.

Step 2: Name this kind of energy.
Energy that travels as waves made of electric and magnetic fields is called electromagnetic radiation. This is the general name for all such waves.

Step 3: See the full family of waves.
Gamma rays, X-rays, ultraviolet, visible light, infrared and radio waves are all members of one big family.

Step 4: Check the wrong options.
Gamma rays, X-rays and UV are only single members of that family. The Sun sends out far more than just these.

Step 5: Pick the term that covers everything.
Only "electromagnetic radiation" covers the whole range of energy the Sun pours onto the Earth.

Step 6: Conclusion.
So the energy received by the Earth from the Sun is best called electromagnetic radiation.
\[ \boxed{\text{Electromagnetic radiation}} \]
