## MTALHAHASSAN2 one year ago 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%?

use $$v = f \, \, \lambda$$ here, $$\lambda = const \implies \large \frac{v_1}{f_1} = \frac{v_2}{f_2}$$
