An unfingered guitar string is 0.68 m long and is tuned to play E above middle C (330 Hz). Required:

a. How far from the nut of the guitar must a fret (and your finger) be placed on this string to play B (494 Hz)?

b. What is the wavelength on the string of this 466-Hz wave?

c. What is the frequency of the sound wave produced in air at 18°C by this fingered string? The speed of sound in air is v≈(331+0.60T)m/s, where T is the temperature in ∘C.

d. What is its wavelength of the sound wave produced in air at 18°C by this fingered string?
