Here's a breakdown:
* What is Refraction? Refraction is the change in direction of a wave as it passes from one medium to another. This change in direction is caused by the change in the wave's speed.
* Why Does It Happen? When a wave travels from one medium to another (like from air to water), its speed changes. This change in speed is caused by the different densities of the two media. The denser the medium, the slower the wave travels. The change in speed causes the wave to bend.
* Examples:
* Light: A common example is the bending of light as it passes from air into water. This is why objects submerged in water appear to be in a different position than they actually are.
* Sound: Sound waves also experience refraction. This is why sounds from a distance seem to come from a different direction than their actual source.
Key Factors Affecting Refraction:
* Angle of incidence: The angle at which the wave hits the boundary between the two media.
* Speed of light in each medium: This is determined by the refractive index of the material.
* Frequency of the wave: The frequency of the wave remains constant as it passes from one medium to another.
