Question

_______ is the radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy.
A. Solar radiations
B. Alpha radiations
C. Beta radiations
D. None of these

Answer 1

Hint:
 The radiations that are emitted by the sun is related to daylight or the rays that come during daylight. These radiations are formed by the process of nuclear fusion in which two or more atomic nuclei are combined to form a single nucleus.

Complete answer:
Solar radiation is the radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. Electromagnetic energy can be defined as the energy that is emitted from objects in the form of an electric and magnetic field. Some of the important examples of electromagnetic energy include microwaves, radio waves, infrared rays, ultraviolet rays, gamma rays, x rays, etc.

The solar radiations give heat and light to the earth. These radiations are also responsible to provide an environment to both the biotic component and abiotic components of the earth. The factors that determine the amount and intensity of the solar radiations that travel towards the earth include latitude, altitude, time of the day, season or climate, etc.
Additional Information – The alpha radiations are also called alpha rays. It consists of two protons and two neutrons. Protons have a positive charge and neutrons have no charge. The net spin of the alpha rays is zero. Alpha decay is one of the important sources of alpha particles.

Hence, the correct answer is option A.

Note:
 The beta radiations are also called a beta particle. These particles have high speed and high energy. These particles are also used to provide healthcare for eyes and bone cancer.
