Reflection and Transmission of Transverse Waves

As shown in the figure, two strings $P$ and $Q$ of length $1 \mathrm{m}$ and $\frac{1}{2} \mathrm{m}$ respectively are connected at $A$ and $B$. $R$ is the junction of both strings. A tension of $100 \mathrm{N}$ is maintained in both strings.  The mass per unit length of strings $P$ and $Q$ are $0.16 \mathrm{kg} {\mathrm{m}}^{-1}$ and $0.25 \mathrm{kg} {\mathrm{m}}^{-1}$ respectively. A pulse of amplitude $2 \mathrm{mm}$ is given at point $A$ it partly reflected and partially transmitted at $R$. Then the amplitude of reflected and transmitted wave is:

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:

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 $\left(\mathrm{V}\mathrm{e}\mathrm{l}\mathrm{o}\mathrm{c}\mathrm{i}\mathrm{t}\mathrm{y}\mathrm{ }\mathrm{o}\mathrm{f}\mathrm{ }\mathrm{s}\mathrm{o}\mathrm{u}\mathrm{n}\mathrm{d}\mathrm{ }\mathrm{i}\mathrm{n}\mathrm{ }\mathrm{l}\mathrm{i}\mathrm{q}\mathrm{u}\mathrm{i}\mathrm{d}\mathrm{ }\mathrm{x}=740\mathrm{ }\sqrt{3}\mathrm{ }\mathrm{m}/\mathrm{s}\mathrm{ }\mathrm{a}\mathrm{n}\mathrm{d}\mathrm{ }\mathrm{i}\mathrm{n}\mathrm{ }\mathrm{w}\mathrm{a}\mathrm{t}\mathrm{e}\mathrm{r}=1480\mathrm{ }\mathrm{m}/\mathrm{s}\right)$

If sound wave travel from air to water, which of the following remain unchanged?
