Find the speed of a wave with wavelength 450 nm and frequency 45 Hz. V l f 450 n m 45 H z 20 250 n m s. Thus in a time of 1 period the wave will travel 1 wavelength in distance.
Longitudinal waves are waves that move in the same direction of the propagation of a wave.
The speed of a longitudinal wave through a liquid or gas depends on the density of the fluid and the bulk modulus of the fluid Here the bulk modulus is defined as V where P is the change in the pressure and the denominator is the ratio of the change in volume to the initial volume and is the mass per unit volume. Thus in a time of 1 period the wave will travel 1 wavelength in distance. You can also enter the wavelength and calculate the frequency. Longitudinal waves are waves in which the displacement of the medium is in the same direction as or the opposite direction to the direction of travel of the wave.
