Correct Answer is:
(3)Longer, the speed of sound is greater in water than in air.
Explanation: We know that
wavelength = velocity/freq
more the velotiy, more will be the frequency

- to ier. 010 10.0 points Middle C has a speed of 1500 m/s in water and 340 m/s in air. Does it have a longer or shorter wavelength in water than in air and why? 1. Longer; water is denser than air. 2. Shorter; water is denser than air. 3. Shorter; the speed of sound is greater in water than in air. he ng 4. Longer; the speed of sound is greater in water than in air.
3. A sound traveling in air has a velocity of 340 m/s and a frequency of 200 Hz. What is its wavelength? What would be the wavelength if the frequency was (a) 2, (b) six times as great? If the sound travels at three times the velocity in a denser medium while the frequency remains the same, what are the wavelengths in each of the preceding cases?
4) The speed of sound in air is 340 m/s. How long does it take for the sound to reach you, it you stand one kilometer away from the source of sound?
A.) The speed of sound in dry air at 20 °C is 343.5 m s-1, and the frequency of the sound from the note D above middle C on the piano is 293.6 s-1 (according to the American standard pitch scale). Calculate the wavelength of the sound and the time it will take to travel 40.1 m across a concert hall. Wavelength = __________ m Time = __________ s 2.)A stretched string with fixed ends has a length of 98.1...
13. Sound travels at 340 m/s in air and 68 m/s in a dense gas. If the wavelength in the air is 2. 0 cm, what is the wavelength of sound of the same frequency in the dense gas? A. 10 cm B. 2. 0 cm C. 0. 40 cm D. 0. 89 cm E. 1. 4 cm F. 4. 5 cm G. 0. 80 cm
the speed of sound is approximately 340 m/s. a certain sound wave has a wavelength of 4.0 m. a. what is the frequency of the sound? b. what is the period of this wave?
Question 2 12 pts The speed of sound in air is 343 m/s, while the speed of sound in water is 1,446 m/s. a) If the frequency of a sound wave is 300 Hz while traveling in water, what is the wavelength of the sound wave? b) If the wave length of a sound wave traveling in air is 3 m, what is the frequency of the sound wave and is it audible to human beings? c) A sound wave...
007 10.0 points If the speed of sound in air is 340 m/s, what is. approximately the length of a shortest air 008 10.0 points A stringed instrument has a maximum string length of 0.4 m and is tuned so that a wave travels along the string at 120 m/s. What is the string's fundamental frequency at this length and wave speed? Answer in units of Hz.
Question 10 The speed of sound in air is 340 m/s. What is the lowest resonant frequency of a hollow tube of length 3 cm which is open at one end and closed at the other?
