Question

Light is a form of _______ that we can detect with our ________
A: energy, ears
B: Corpuscles, eyes
C: Energy, eyes
D: Sensation, skin

Answer 1

We know that there are natural and artificial sources of light. The biggest natural source of light is the sun. We know that whenever the sun is up in the sky, we can clearly see things whereas after sunset that is during the night time we are unable to see things.

Complete step by step answer:
Light, also known as visible light is the electromagnetic radiation that is within the electromagnetic spectrum. As the name suggests, it enhances visibility. We know that human eyes are the parts in our body that help us to detect visibility. We see things with the help of our eyes. Hence, we can say that we detect light with our eyes.
Also, we can define light in the form of a stream of photons or massless packets that travel with the velocity of light by holding wave-like properties. We can say that photons are massless packets of energy. This makes us say that light is nothing but a form of energy.
Therefore we can say that light is a form of energy that we can detect with our eyes.
Hence, option C is the correct answer among the given options.

Note: Human eyes help us to identify and detect light as the cells in our retina called photoreceptors are capable of converting light into electrical signals. These cells are in our retina and get activated when light falls into the retina. The electrical signal travels to the optic nerve in the brain, where it gets processed as images that we see.
