(Hint: Compare the speed of sound in water and air in the table.) Can you calculate the speed of sound in air and the wave speed on the string in the Violin simulation below? The product of the wavelength and frequency can be used to determine the speed of sound in air and wave speed on the violin string: The speed of sound is the distance that sound waves travel in a given amount of time.
