Question

Answer

The correct option is Option B.

The phenomenon of light responsible for the working of the human eye is refraction.

Answer

The phenomenon of light responsible for the working of a human eye is refraction.

Answer

Because  our eyes  have  retina which  reflects the light

Answer

Refraction
Refraction is the phenomenon of light bending as it passes through different mediums. It occurs when light travels from one medium to another with a different optical density, causing the light rays to change direction. Refraction is responsible for the working of the human eye.

Working of the Human Eye
The human eye is a complex optical system that allows us to see the world around us. It consists of various components, including the cornea, lens, and retina.

Cornea and Lens
The cornea is the transparent outermost layer of the eye, while the lens is located behind the cornea. Both the cornea and lens play a crucial role in the refraction of light.

When light enters the eye, it first passes through the cornea. The cornea refracts the light, bending it towards the lens. The lens further refracts the light and focuses it onto the retina at the back of the eye.

Retina and Optic Nerve
The retina is a layer of light-sensitive cells located at the back of the eye. It contains specialized cells called photoreceptors, which convert light into electrical signals that can be interpreted by the brain.

When light reaches the retina, it stimulates the photoreceptor cells. These cells generate electrical signals, which are then transmitted to the brain via the optic nerve. The brain processes these signals and creates the visual perception of the objects we see.

Importance of Refraction
Refraction is crucial for the working of the human eye because it helps in focusing the light onto the retina. Without refraction, the light entering the eye would not converge properly, resulting in a blurry image on the retina. The bending of light by the cornea and lens ensures that the light rays converge at a precise point on the retina, allowing for clear and focused vision.

Conclusion
In conclusion, the phenomenon of refraction is responsible for the working of the human eye. It allows light to be bent and focused onto the retina, where it is converted into electrical signals and transmitted to the brain for visual perception. Without refraction, our vision would be blurry and unfocused.
