Here are some common units for wave velocity:
* Meters per second (m/s): This is the standard unit in the International System of Units (SI).
* Kilometers per hour (km/h): This is commonly used for describing the speed of cars and other vehicles.
* Miles per hour (mph): This is commonly used in the United States.
* Feet per second (ft/s): This is sometimes used in engineering applications.
The specific units used will depend on the context. For example, the velocity of light waves is often expressed in meters per second, while the velocity of sound waves is often expressed in meters per second or kilometers per hour.
