Frequency = \\frac{1}{Time Period}
Ultrasonic waves are sound waves with frequencies higher than the upper audible limit of human hearing.
A wave is a disturbance in a medium that carries energy without net movements of particles.
Audible range means the range of frequencies that can be heard by the humans
Think about the properties of a sound wave.
Think about the propagation of sound in a medium.
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\\)
The sensation of frequency is known as the pitch of sound waves.
Frequency = \\(\\frac{1}{Time Period}\\)
