Ultrasound waves have a ______ frequency and a _______ wavelength when compared to infrasound waves.
Two waves A and B have wavelength 0.01 ∘A and 9000 ∘A respectively.
(a) Name the two waves.
(b) Compare the speeds of these waves when they travel in vacuum.
A certain sound wave travels through water with a certain wavelength, frequency, and wave speed. A second sound wave with twice the frequency of the first wave then travels through the same water. What is the second waves wavelength and wave speed compared to those of the first wave?
