Reflection of Transverse and Longitudinal Waves

A man standing on a cliff claps his hand hears its echo after $1 \mathrm{s}$. If sound is reflected from mountain and velocity of sound in air is $340 \mathrm{m} {\mathrm{s}}^{-1}$. Then, the distance between the man and reflection point is,

Phase difference between the incident and reflected wave, when the reflection happens at fixed end:

When a longitudinal wave is incident at the boundary of denser medium, then :

Describe the reflection of a wave from fixed end.

In an empty room why is it that a tone sounds louder than in the room having things like furniture etc.

When a longitudinal wave is incident at the boundary of denser medium, then

Explain the reflection of sound waves from curved surface.

A string is clamped at both ends such that one end of the string is at x = 0 and the other is at x = $L$. When the string vibrates in fundamental mode, amplitude of the mid-point O of the string is $a$, and tension in the string is $T$. What is the total energy of oscillation stored in the string?

The pulse of a wave travels along a stretched string and reaches the fixed end of the string. It will be reflected back with:

One end of a thin metal tube is closed by thin diaphragm of latex and the tube is lower in water with closed end downward. The tube is filled with a liquid 'x'. A plane progressive wave inside water hits the diaphragm making an angle 'θ' with its normal. Assuming Snell's law to hold true for sound. Maximum angle 'θ' for which sound is not transmitted through the walls of tube is $\left(\mathrm{V}\mathrm{e}\mathrm{l}\mathrm{o}\mathrm{c}\mathrm{i}\mathrm{t}\mathrm{y}\mathrm{ }\mathrm{o}\mathrm{f}\mathrm{ }\mathrm{s}\mathrm{o}\mathrm{u}\mathrm{n}\mathrm{d}\mathrm{ }\mathrm{i}\mathrm{n}\mathrm{ }\mathrm{l}\mathrm{i}\mathrm{q}\mathrm{u}\mathrm{i}\mathrm{d}\mathrm{ }\mathrm{x}=740\mathrm{ }\sqrt{3}\mathrm{ }\mathrm{m}/\mathrm{s}\mathrm{ }\mathrm{a}\mathrm{n}\mathrm{d}\mathrm{ }\mathrm{i}\mathrm{n}\mathrm{ }\mathrm{w}\mathrm{a}\mathrm{t}\mathrm{e}\mathrm{r}=1480\mathrm{ }\mathrm{m}/\mathrm{s}\right)$

Two strings with masses per unit length of $25 \mathrm{g}\mathrm{c}{\mathrm{m}}^{-1}$ and $9 \mathrm{g}\mathrm{c}{\mathrm{m}}^{-1}$ are joined together in series. The reflection coefficient for the vibration waves is

Sound waves of v=600Hz fall normally on a perfectly reflecting wall. The shortest distance from the wall at which all particles will have maximum amplitude of vibration will be (speed of sound=$300m{s}^{-1}$)
