The phase difference between the two particles situated on both the sides of a node in a stationary wave is ... $^o$.

The stationary wave $y = 2a \sin kx \cos \omega t$ in a stretched string is the result of the superposition of $y_1 = a \sin(kx - \omega t)$ and

Match Column - $A$ with Column - $B$.

Column - $A$	Column - $B$
$(a)$ Minimum change in pressure	$(i)$ Antinodal point
$(b)$ Maximum change in pressure	$(ii)$ Nodal point

$A$ wave is reflected from a rigid support. The change in phase on reflection will be

The vibrations of a string of length $60 \, cm$ fixed at both ends are represented by the equation $y = 2 \sin \left( \frac{4 \pi x}{15} \right) \cos (96 \pi t)$,where $x$ and $y$ are in $cm$. The maximum number of loops that can be formed in it is

Stationary waves of frequency $300\, Hz$ are formed in a medium in which the velocity of sound is $1200\, m/s$. The distance between a node and the neighbouring antinode is ... $m$.
