Refraction of light is the bending of light as it passes through different mediums, such as air, water, or glass. This is caused by a change in the speed of light as it travels from one medium to another.
Refraction occurs due to the change in the speed of light as it travels from one medium to another. This change in speed causes the light to bend, as different mediums have different densities and therefore affect the speed of light differently.
The law of refraction, also known as Snell's law, states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the speeds of light in the two mediums. This can be represented by the equation sin θ1/sin θ2 = v1/v2, where θ1 is the angle of incidence, θ2 is the angle of refraction, v1 is the speed of light in the first medium, and v2 is the speed of light in the second medium.
Refraction can cause objects to appear distorted or shifted when viewed through different mediums. This is because the light rays from the object are bent as they pass through the medium, changing the direction in which they travel. This can result in a change in the apparent size, shape, and position of the object.
Refraction has many practical applications, such as the functioning of lenses in glasses and cameras, the formation of rainbows, and the bending of light in optical fibers for communication. It is also used in the design of telescopes, microscopes, and other optical instruments.
