On which of the following principle does the human eye work?

Correct option is C

The correct answer is (c) Refraction of light.
· The human eye works on the principle of refraction of light. When light enters the eye, it passes through several structures, including the cornea and the lens, which refract (bend) the light rays to focus them on the retina at the back of the eye.
· The retina contains photoreceptor cells that convert the light signals into electrical signals, which are then transmitted to the brain via the optic nerve, allowing us to perceive images.
· The lens in the eye adjusts its shape to focus light properly, a process known as accommodation, ensuring clear vision at different distances.
· Myopia (nearsightedness) and hyperopia (farsightedness) are vision problems caused by improper refraction of light in the eye.
· Corrective lenses like glasses or contact lenses adjust the refraction of light to compensate for these vision issues.

· Dispersion of light: Refers to the splitting of light into its component colors, not related to how the eye functions.
· Reflection of light: While light can reflect off surfaces, the eye primarily uses refraction to focus light.
· Scattering of light: Refers to the spread of light in different directions, not relevant to the function of the eye
