a 2m long string of mass 10g is clamped at boths ends.the tension in the string is 150N.the string is plucked so that it oscillate.what is the wavelength and frequency of the resulting wave it is produce a standing wave with two antinodes?

With two antinodes, the wavelength of the traveling waves is 2.0 meters.
The wave speed is
V = sqrt(T/(mass per length))
= sqrt(150/(0.010/2)= 173.2 m/s
Frquency = V/(wavelength)= 86.6 Hz
