6. [a] Write three factors on which speed of sound depends[b]A bat can hear sound at frequencies up to 120KHz. Determine the wavelength ofsound in air at this frequency.(Take speed of sound in air as 344m/s.)

Answer»

Speed of sound depends primarily on thedensityand viscosity of the medium through which it propagates.

Sotemperature,humidity(ifnonliquid medium) andpressureare also factors as they impact thedensityand viscosity of the medium, especially if the sound wave propagates through fluids.
