Astring (with uniform mass density) is attached to a wave generator with variable frequency to create standing wave patterns. the string goes over a pulley and is connected to a mass (which can be varied) to create tension in the string. mass on a string over pulley 1) if the frequency is changed (while the mass is held fixed), what else will change?

on changing frequency, only wavelength will change.

Explanation:

We know that

Velocity of wave

..................(1)

............(2)

λ= wavelength

\nu= frequency of wave

T=time period of wave

\mu= mass density of string

As the mass has not changed. Tension T remains same.

Therefore , on changing frequency, only wavelength will change.

answer: b.

explanation:

object 2 because all the other ones are wrong
