This means the period of a wave is the inverse of the frequency, so the formula for wave period is wavelength divided by velocity.
What is the formula for sound waves?
v=√γRTM. Note that the velocity is faster at higher temperatures and slower for heavier gases. For air, γ = 1.4, M = 0.02897 kg/mol, and R = 8.31 J/mol • K. If the temperature is TC = 20 °C (T = 293 K), the speed of sound is v = 343 m/s.
What does period mean in sound waves?
The period of a wave is the time required for one complete cycle of the wave to pass by a point. So, the period is the amount of time it takes for a wave to travel a distance of one wavelength. Amplitude: The amplitude of a sound is represented by the height of the wave.
