If the speed of wave propagation remains constant, an increase in the wavelength will result in a decrease in the frequency. The reverse is also true. b) Since the wave velocity is equal to the product of the frequency times the wavelength, , increasing the temperature will increase the wavelength since the frequency is the same. The intensity of wavelength increases with increase in temp and the wavelength itself decreases so the wavelength is inversely proportional to temp and the frequency is directly proportional to temp, but in case of sound waves frequency is not effected the change in speed is due to the fact that the average kinetic .
