Speed of Sound in Different MediaQuiz - Solve & Score
Q1. A tuning fork in a school lab vibrates at 256 Hz and sets up a wave whose wavelength in air is 1.32 m; what speed does the sound travel at?
- A.0.0052 m/s
- B.337.92 m/s
- C.193.939 m/s
- D.257.32 m/s
Answer: B. 337.92 m/s
Speed v = frequency * wavelength = 256 Hz * 1.32 m = 337.92 m/s.
Q2. A street musician plucks a string that emits a note of frequency 512 Hz, and the sound waves are measured to be 0.66 m apart; how fast is the sound moving?
- A.0.0013 m/s
- B.775.758 m/s
- C.512.66 m/s
- D.337.92 m/s
Answer: D. 337.92 m/s
Speed v = frequency * wavelength = 512 Hz * 0.66 m = 337.92 m/s.
Q3. During a physics demonstration a loudspeaker driven at 480 Hz produces waves of wavelength 0.7 m in the room; what is the speed of the sound?
- A.336 m/s
- B.685.714 m/s
- C.480.7 m/s
- D.0.0015 m/s
Answer: A. 336 m/s
Speed v = frequency * wavelength = 480 Hz * 0.7 m = 336 m/s.
