F is the frequency of wave v is the speed of wave and. The equation for wavelength is. Sound pressure level decibels db P sound wave pressure newtonsmeter 2.
The equation for wavelength is.
As we know for a sinusoidal wave moving with a constant speed the wavelength of the wave is inversely proportional to its frequency. Wavelength l 700 nm Velocity of light v 3 x 108 ms. L is the wavelength of wave. Sound pressure level decibels db P sound wave pressure newtonsmeter 2.
