Refraction is the bending of light as it passes through different mediums, such as air, water, or glass.
Refraction occurs when light travels through a medium with a different density than the medium it was previously traveling through. This change in density causes the light to change speed and direction.
The cause of refraction is the change in speed and direction of light as it passes through mediums with different densities. This change in density can be caused by different temperatures or compositions of the medium.
Refraction is typically measured using the angle of incidence and the angle of refraction. The angle of incidence is the angle at which light enters a medium and the angle of refraction is the angle at which light exits the medium. The ratio of these angles can be used to calculate the refractive index, which is a measure of how much the light is bent.
Refraction has many practical applications in our everyday lives. Some examples include eyeglasses, telescopes, cameras, and microscopes. It is also used in the design of lenses, prisms, and other optical instruments. Refraction is also important in understanding the behavior of light in different mediums, which is essential in fields such as meteorology and oceanography.
