Light refraction is the bending of light as it passes from one medium to another, such as from air to water. When a single ray of light enters a different medium at an angle, it changes speed and bends, or refracts, towards or away from the normal line, which is an imaginary line perpendicular to the surface. This bending is due to the change in the speed of light in different mediums, causing the ray to change direction.

How does the concept that light has momentum impact our understanding of the behavior of photons?
The concept that light has momentum affects our understanding of photons by showing that they have both energy and momentum, which helps explain their behavior, such as reflection and refraction. This understanding is important in fields like physics and astronomy.
Application of refraction in physics?
One interesting application is the use of lenses, for example in telescopes and microscopes. Lenses use refraction to concentrate light.Another application is the use of radio waves for communication. Radio waves are often said to be reflected back from the upper atmosphere, but I understand that this is not really reflection, but refraction.
What is the difference between deviation and refraction in physucs?
Deviation refers to the bending of light as it passes through a medium or interface between two different mediums, causing the light to change direction. Refraction specifically refers to the bending of light as it passes from one medium to another, due to a change in the speed of light. So, deviation is a broader concept that includes refraction as a specific type.
Does meaning of normal change when representing refraction?
In the context of refraction, "normal" refers to an imaginary line perpendicular to the surface at the point where the light ray hits. It is used as a reference point to determine angles of incidence and refraction. The concept of "normal" remains the same in this context as it is used in optics to describe the behavior of light waves.
Explain why the index of refraction for air (a gas) is smaller than the index of refraction for a solid like glass?
The index of refraction is a measure of how much light slows down when passing through a medium. The molecules in gases are more spread out compared to solids like glass, so there's less interaction with light, resulting in a smaller index of refraction for air compared to glass.

Does the Particle Model explain Refraction?
Yes, the Particle Model can explain refraction by considering light as a stream of particles (photons) that change speed and direction when passing through different mediums, causing the bending of light rays.
What is the relationship between refraction and intensity of light?
Refraction does not affect the intensity of light; intensity remains constant through refraction. Refraction only changes the direction of light as it passes through different mediums of different densities. The intensity of light can change due to absorption or scattering when light interacts with particles in the medium.
How does refraction change light?
What is Refraction?? What is Refraction??
Will light bend when it enters new material?
Yes. Many solutions have unique refractive indeces. Refraction is the concept.
What is the relation of speed of light through a substance and the ange of refraction?
The speed of light in a single substance doesn't tell you anything about refraction. The angle of refraction at the boundary between two substances depends on the speed of light in both of them ... and also, let us not forget, on the angle of incidence at the boundary.
When does light undergo refraction?
light undergoes refraction when the matter changes the speed of light
