The lowest frequency of a guitar string with a length 0.65 m is 248 Hz. What is the speed of the wave on this string? Same guitar, same string as in Question 1. If the mass per unit length of the string is 0.5g/m, what is the tension on the string? A tuning fork produces two maxima, n =1 and n =3, separated by 48 cm.

What would be the separation of the two maxima (L3/4−L1/4) in a standing wave apparatus like the one you used in the lab, if the tube were filled with helium gas? Using Eq.
