What is the wavelength of the wave

Reference no: EM13541026

A sound wave travels in air with frequency 1372 Hz. (Assume the temperature of the air is 20 degrees C)

a) If we can hear the sound at a level of 25 dB, what is its intensity? (The minimum intensity audible to humar ear is I= 1.0 x 10^-12 W/m^2)

b) What is the wavelength of the wave?
