Refraction is the bending of light as it passes through different mediums, such as air, water, or glass. This bending occurs because the speed of light changes as it moves from one medium to another.
Refraction occurs due to the change in speed of light when it moves from one medium to another. This change in speed causes the light to bend, as each medium has a different index of refraction, which is a measure of how much the speed of light changes in that medium.
The change in speed of light during refraction is caused by the change in the density of the medium. Light travels slower in denser mediums, such as water or glass, than in less dense mediums, such as air.
The angle of incidence is the angle at which light enters a medium, while the angle of refraction is the angle at which it bends as it passes through the medium. The relationship between these two angles is described by Snell's Law, which 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.
Refraction is a common phenomenon that occurs in our daily lives. Some examples include the bending of light as it passes through a glass of water, the formation of rainbows due to the refraction and dispersion of sunlight, and the use of lenses in glasses and cameras to change the direction of light. It is also utilized in various optical instruments, such as microscopes and telescopes, to magnify and focus light.
