Exercise-1

In stationary waves at nodes -

The equation $y=0.15\sin 5x\cos 300t$, describes a stationary wave. The wavelength of the station any wave is

There are some points in a stationary waves which -

A plane wave is described by the equation $y=3\cos \left(\frac{x}{4}-10t-\frac{\pi }{2}\right).$ The maximum velocity of the particles of the medium due to this wave is - 

A stationary wave is represented by $y=A\sin \left(100t\right)\cos (0.01x),$ where $y$ and $A$ are in millimeters, $t$ is in seconds and $x$ is in metres. The velocity of the wave is 

Equation $y=2a\cos \left(kx\right)\sin \left(\omega t\right)$, represents

In the $n^{\mathrm{th}}$ normal mode of vibration of a string, there are
