An ultrasonic sensor emits sound waves with a frequency of 55 kHz. If the wavelength of the sound waves is 0.015 meters, what is the velocity of the waves?

Velocity = Frequency × Wavelength
Velocity = 55,000 Hz × 0.015 meters
Velocity = 825 meters per second

The velocity of the ultrasonic waves is 825 meters per second.
