Refraction Vs Reflection

Refraction is the bending of light as it passes from one medium to another with a different density, such as air to water. This change in speed causes the light waves to change direction, which is why objects may appear distorted or displaced when viewed through different materials. The degree of bending is described by Snell's Law, which relates the angles of incidence and refraction to the indices of refraction of the two media involved.

Reflection is the bouncing back of light waves when they encounter a surface that does not absorb the light. This phenomenon occurs at the interface between two different media, such as air and a mirror, and can be described by the law of reflection, which states that the angle of incidence is equal to the angle of reflection. Reflection is responsible for the formation of images in mirrors and contributes to our perception of the world around us.
