Suppose you listen to a 440 Hz sound wave, which travels throughthe air with speed 344 m/s. How many compressions per second entereach of your ears?A) 1/344B) 344C) 1/440D) 440
The wavelength of one sound wave is 0.81 m. The wavelength of asecond sound wave is a little bit longer. When the two sound wavesare superimposed on each other, we hear a 3.2 -Hz beat. Find thedifference (mm) in their wavelengths. The speed ofsound is 343 m/s. Give the answer to 2 significant figures.
The frequency of a wave increases. What happens to the distancebetween successive crests if the speed remains constant?a) it remains the sameb) it increasesc) it decreasesd) it cannot be determined from the information given
