Think about the properties of a sound wave.
The sensation of frequency is known as the pitch of sound waves.
Wavelength is the distance between two successive crests or troughs of a wave. Frequency is the number of occurrences of a repeating event per unit of time.
Distance = \\(Speed\\times Time\\)
Ultrasonic waves are sound waves with frequencies higher than the upper audible limit of human hearing.
Audible range means the range of frequencies that can be heard by the humans
Frequency = \\frac{1}{Time Period}
Frequency = \\(\\frac{1}{Time Period}\\)
A wave is a disturbance in a medium that carries energy without net movements of particles.
Think about the propagation of sound in a medium.
