* Change in Speed: The wave's speed changes as it transitions between mediums. This is because the wave interacts differently with the particles of each medium.
* For example, light travels slower in water than in air.
* Change in Direction: The wave's direction changes, bending at the boundary between the mediums. This bending is caused by the change in speed.
* The amount of bending depends on the angle at which the wave strikes the boundary and the difference in the wave's speed in the two mediums.
* Change in Wavelength (for some waves): The wavelength of the wave might also change. However, the frequency of the wave remains constant.
* For example, light's frequency stays the same, but its wavelength gets shorter when it travels from air to water.
Here's a simple analogy:
Imagine a car driving on a smooth road then suddenly encountering a rough, uneven patch. The car's speed changes, and its path bends slightly as it transitions from the smooth surface to the rough one. Similarly, a wave's speed and direction change as it moves from one medium to another.
Key Points:
* Refraction is a common phenomenon: It happens to all types of waves, including light, sound, and water waves.
* Snell's Law describes the relationship between the angle of incidence, angle of refraction, and the indices of refraction of the two mediums.
