Coils_1.821.2 Hz2.184 m/s6. As the wavelength of a wave in a medium increases, its frequency will _____.a. decreaseb. increasec. remain the same7. The speed of a wave depends upon ...the properties of the medium through which the wave travels the wavelength of the wave. the frequency of the wave. both the wavelength and the frequency of the wave. 8. Dawn and Aram have stretched a slinky between them and begin experimenting with waves. As the frequency of the waves is doubled,the wavelength is halved and the speed remains constant the wavelength remains constant and the speed is doubled both the wavelength and the speed are halved. both the wavelength and the speed remain constant. CBA9. Is the following diagram showing a longitudinal wave or a transverse wave?
