Standing Wave Visualization

Q. 45.In a resonance pipe the first and second resonances are obtained at depths 23.7 cm and 72.3 cm respectively. Then the end correction will be a- 0.6 cm b- 1.2 cm c- 0.8 cm d- 2.4 cm

Q. In a stationary wave, all particles are at rest at the same time

in every period of oscillation.

1. twice
2. only once
3. thrice

Q.

Is standing ann stationary waves same?and is stationary waves continuous or it stops after sometimes?

Q. A stretched string is vibrating according to the equation $y=5\sin \left(\frac{\pi x}{2}\right)\cos 4\pi t$, where $y$ and $x$ are in $\text{cm}$ and $t$ is in $\text{sec}$. The distance between two consecutive nodes on the string is

1. $2\text{cm}$
2. $4\text{cm}$
3. $8\text{cm}$
4. $16\text{cm}$
