Question

Light is a form of energy.
a).True
b).False

Answer 1

Hint:Energy is defined as a quantitative property that can be transferred to an object either to perform some work or to heat following the law of conservation of energy that states that it can neither be created nor be destroyed.

Complete step-by-step answer:
Sun is the ultimate source of light which is defined as the electromagnetic radiation emitted from different objects like bulbs, lasers etc.
When an atom is heated up, it produces photons because of the excitement of the electrons. Light also contains such photons which are considered as the small packets of energy. Light travels from the Sun to Earth and from different light sources in the form of a wave thus they possess the kinetic energy which allow them to travel through space even where there is no air.
Light is also the key element in the photosynthesis of plants, where it helps in creating food by converting itself in the form of energy used by plants. And thus, making light the only source of generation of food among the living organisms.
Thus, light is also a form of energy.

Hence, option a is the correct answer.

Additional information:
There are many uses of light energy,
It helps to make things visible so that human eyes can see it
Helps plants to grow and make their food
Major source of solar energy
Used by many space stations and satellites

Note: To check, whether anything is a form of energy we should apply the law of conservation of energy, to check if it is getting converted into any other form of energy. Even in our daily life, we use calculators which get power from solar cells.
