A wire is stretched and fixed at two ends. Transverse stationary waves are formed in it. It oscillates in its third overtone mode. The equations of stationary wave is-
$$ y=A \sin k_k \cos \omega t
Choose the correct options.

Option: 1

Amplitude of consituent waves is \frac{A}{2}


Option: 2

The wire oscillates in 3 loops


Option: 3

The length of the wire is \frac{4\pi}{K}


Option: 4

Speed of stationary wave is \frac{W}{K}


Answers (1)

l=4 \frac{\lambda}{2}=2 \lambda \Rightarrow 2\left(\frac{2 \pi}{K}\right) \quad\left[\because K=\frac{2 \pi}{\lambda}\right]

l=\frac{4 \pi}{K}
