Question

Which of the following energy conversion takes place in the figure given here?

A. ${\text{solar}} \to {\text{electrical}}$
B. \[{\text{solar}} \to {\text{light}} \to {\text{heat}}\]
C. ${\text{solar}} \to {\text{electrical}} \to {\text{heat}} \to {\text{light}}$
D. ${\text{solar}} \to {\text{electrical}} \to {\text{light}} \to {\text{heat}}$

Answer 1

Hint: The process of transferring energy from one form to another is known as energy transformation of energy conversion. Energy is a quantity in physics that has the ability to perform work or create heat. And here in this question we will simply write the energy conversion.

Complete answer:
Here in above figure we can see that firstly the sun light is falling on a solar panel and we can say that when light falls on solar panel the solar panel converts the light energy into electrical energy and in next stage we can see in diagram is this electrical energy is used to light up the lap and can say that the electrical energy is converted into light energy and can say light energy is also a form of heat and produces heat so we can say that the light energy is then converted into heat energy. So, from the above solution we can conclude that the conversion of energy takes place as solar to electrical and then electrical to light and then light to heat.

Hence option D is the correct answer.

Note: Solar panels are used to convert light energy into electrical energy and this form of energy is available in plenty as the sun is the great source of light energy and also this form of energy is the cleanest form of energy and our world is trying to relay a completely clean source of energy.
