Question

Choose the correct option for solar energy is due to:
A) Chemical reaction
B) Combustion reaction
C) Nuclear fusion reaction
D) Nuclear fission reaction

Answer 1

Hint: Solar energy is the major source of renewable energy. Maximum power generation can be done by proper utilization of solar radiation. The light energy in solar radiation is directly converted into electrical energy by the Photovoltaic effect in photovoltaic cells. The energy radiating from the sun is known as solar energy.

Complete answer:
 In nuclear reaction two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles. Mass difference between the reactants and the products is manifested as either the release or the absorption of energy. Thus this difference in masses arises due to the difference in atomic bonding energy between the nuclei before and after the reaction.
The solar energy is generated in the core of the sun and the process is known as nuclear fusion. The extreme high temperature and pressure which is in the sun cause the nuclei of hydrogen atoms to fuse this reaction is called nuclear fusion.
The correct option is D.

Note: India receives solar radiation almost throughout the year which amounts to hours of sunshine this is equal to more than 5000 trillion kW. The use of solar energy can reduce the dependence of non-renewable sources on high amounts of solar energy wasted in the form of heat. A thermoelectric energy harvesting (TEH) technology utilizes waste heat energy for power generation.
