A wave has a wavelength of 4.9 m and a velocity of 9.8 m/s. The medium through which this wave is traveling is then heated so that the velocity is doubled.If the frequency remains constant, what is the wavelength of the heated wave?

The original frequency is 9.8 m/s ÷ 4.9 m = 2 Hz. When the speed doubles to 19.6 m/s and frequency stays at 2 Hz, the wavelength is 19.6 m/s ÷ 2 Hz = 9.8 m, so the heated wave has a wavelength of 9.8 m.
