$A$ wave can transmit ...... from one place to another.

Which property distinguishes progressive waves from stationary waves?

$A$ musical instrument $P$ produces sound waves of frequency $n$ and amplitude $A_P$. Another musical instrument $Q$ produces sound waves of frequency $\frac{n}{4}$. The waves produced by $P$ and $Q$ have equal energies. If the amplitude of waves produced by $P$ is $A_P$,the amplitude of waves produced by $Q$ will be: (in $A_P$)

The intensity ratio of two waves is $1 : 16$. The ratio of their amplitudes is

With the propagation of a longitudinal wave through a material medium,the quantities transmitted in the propagation direction are

If the ratio of the amplitudes of two waves is $2:1$,then the ratio of their maximum and minimum intensity is:
