# Question

Apiece of steel string is under tension.

(a) If the tension doubles, the transverse wave speed (1) doubles, (2) halves, (3) increases by √2, (4) decreases by √2. Why?

(b) If the linear mass density of a 10.0-m length of string is and it is under a tension of 9.00 N, what is the transverse wave speed in the string?

(c) What are its waves’ natural frequencies?

On a violin, a correctly tuned A string has a frequency of 440 Hz. If an A string produces sound at 450 Hz under a tension of 500 N, what should the tension be to produce the correct frequency? String A has twice the tension but half the linear mass density as string B, and both strings have the same length. (a) The frequency of the first harmonic on string A is (1) four times, (2) twice, (3) half, (4) ¼ times ...A 0.500-kg mass is attached to a vertical spring and the system is allowed to come to equilibrium. The mass is then given an initial downward speed of 1.50 m/s. The mass travels downward 25.3 cm before stopping and ...(a) Why does it seem particularly quiet after a snowfall? (b) Why do empty rooms sound hollow? (c) Why do people’s voices sound fuller or richer when they sing in the shower?
