Question

In a guitar string that vibrates at 440 Hz, the speed of a wave is 365.0 m/s. What will the pitch be if the tension in the string is changed such that the speed of the wave:
a)Is reduced to 350.0 m/s?
b)Is increased by 20.0%?
c)Is decreased by 15%?

Answer 1

use \(v = f \, \, \lambda\)

here, \( \lambda = const \implies \large \frac{v_1}{f_1} = \frac{v_2}{f_2} \)
