Wavelength:
* Remains the same. When a water wave reflects off a barrier, its wavelength (the distance between two crests or troughs) doesn't change.
Velocity:
* Remains the same. The speed of the water wave (its velocity) also doesn't change upon reflection.
Key Points:
* Reflection is a change in direction, not a change in properties. Reflection causes a wave to bounce off a surface at an angle equal to its angle of incidence. The wave's fundamental characteristics (wavelength and velocity) are preserved.
* Factors affecting water wave speed: The speed of a water wave is primarily determined by the depth of the water. Deeper water allows waves to travel faster.
Example:
Imagine a water wave approaching a vertical wall. The wave hits the wall and changes direction, moving away from the wall at the same angle as it approached. The wave's wavelength and velocity are the same before and after reflection.
