Here's a breakdown:
* Refraction occurs because the wave's speed changes as it moves from one medium to another. This change in speed causes the wave to bend.
* The amount of bending depends on the angle at which the wave hits the boundary between the two materials, and the difference in speed of the wave in each material.
* A higher speed difference between the two materials leads to a greater angle of refraction.
Here's a simple example:
Imagine a light ray traveling from air into water. Light travels slower in water than in air. When the light ray hits the water's surface, it bends towards the normal (an imaginary line perpendicular to the surface).
Key Points:
* Refraction is a phenomenon that applies to all types of waves, including light, sound, and water waves.
* The direction of bending depends on whether the wave is slowing down or speeding up as it enters the new medium.
* Refraction is the reason why objects appear to be distorted when viewed through water, or why rainbows form in the sky.
