How does amplitude affect wave speed

Sound waves travel faster if you increase the temperature of the air. Changing the frequency or amplitude of the waves will not change the wave speed, since those are not changes to the properties of the medium .

If you mean “speed” as the speed of the source of the wave (velocity would be better to take into consideration direction), then the wavelength will shorten ( bunch together) as the source moves toward the observer and lengthen moving away, with corresponding frequency change ; so for a longitudinal sound wave, the …

Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency .

When frequency increases, speed increases and vice versa.3 Mar 2016
