A guitar string of length 72.8 cm (which might be out of tune) has been plucked and is producing a note of frequency 334 Hz. (a) What is the speed of transverse traveling waves on this guitar string? Give your answer in m/s. HINT: The note you hear is produced by the vibrational mode of the string which has the fundamental (lowest possible) frequency. Draw a picture of the string vibrating in that mode and determine the wavelength of the traveling waves which combine to produce the standing wave that you have drawn. m/s (b) In the sound wave that is traveling from the guitar string to your ears, what is the distance between adjacent condensations? (For the speed of sound in air use the value, at 20 degrees Celsius, from the inside front cover of your textbook.) m
