Reflection of Waves

Describe the reflection of the wave from a free end.

Describe the reflection of a wave from fixed end.

Write the equation of reflected wave which is reflected from a free end if the equation of incident wave is $y(x,t) = a\sin (kx-\omega t)$. 

Write the equation of reflected wave which is reflected from a fixed end if the equation of incident wave is $y(x,t) = a\sin (kx-\omega t)$. 

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

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

A progressive wave $y=a\sin \left(kx-\omega t\right)$ is reflected by a rigid wall at $x=0$. Then the reflected wave can be represented by

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=$300m{s}^{-1}$)

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