A man is playing the lowest note on a 5 string bass guitar, which has a frequency of f= 30 s, and it corresponds to the lowest frequency standing wave on the heaviest string on the guitar. a) If the wavelength of this standing wave on the guitar string is 1 = 2 m, then how long is the portion of the string that is free to move? b) What is the wave speed of traveling waves on this guitar string? c) This 30 Hz tone is being amplified by a powerful loudspeaker. What is the wavelength of the sound wave emitted by the speaker? You may approximate the speed of sound as 300 m/s. d) What is the frequency heard by a woman driving at a speed of 30 m/s away from the guitar player?
