question mark

one end of a taut string of length 3 m along the x axis is fixed at x=0.the speed of the waves in the string is 100 m/s.the other end of the string is vibrating in the y direction so that stationary waves are set up in the string.the possible waveform(s) of these stationary wave is?

[A,C,D]

Taking y(t)=Af(x)g(t) & Applying the condtions:

1; here x=3m is antinode & x=0 is node

2; possible frequencies are odd multiple of fundamental frequency.

where,

 

V fundamental = v / 4l = 25/3 Hz
