Classification of Wave

Sound and light waves are_____.

Energy is not propagated by which of the following waves?

What are the differences between mechanical and non-mechanical waves?

Transverse waves cannot travel through

The waves in a string are transverse in nature.

For a three-dimensional wave represented by

$f(\overrightarrow{r}, t)=A\sin \left(\overrightarrow{k}·\overrightarrow{r}-\omega t\right)$

The direction of $\overrightarrow{k}$ is

Which one of the following is an example of a one-dimensional wave?

Which one of the following principles can be used to explain propagation of wave in two or three dimension?

For a three-dimensional wave of function $\psi \left(x, y, z, t\right)$ and wave velocity $v$, the equation for the wave can be given by

Electromagnetic waves are produced by-

A uniform rope of mass $\mathrm{m}$ and length $\mathrm{L}$ hangs from a celling. The speed of transverse waves in the rope at a point at a distance $\mathrm{x}$ from the lower and of the rope is

If tension of sonometer wire is made four times, then its frequency will change by a factor of:

A string of length $2\mathrm{m}$ has $10\mathrm{g}$ mass. The speed of the simple harmonic wave produced in it is $40 \raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{$\sec $}\right.$. The tension in the string is

If the mass of $0.72 \mathrm{m}$ long steel wire is $5.0\times {10}^{-3} \mathrm{kg}$ then the speed of produced transverse waves on the wire under $60\mathrm{N}$ tension in the wire is

Two identical stones are dropped into opposite ends of a puddle. The waves created by the stones travel towards each other. What happens in the middle of the puddle?

Assertion: In longitudinal stationary waves, displacement node is pressure antinode and vice-versa.

Reason: At the point of displacement, node particles are at rest and variation in pressure is maximum.

The distance between two consecutive crests in a wave train produced in a string is $5 \mathrm{cm}$. If $2$ complete waves pass through any point per second, the velocity of the wave is

A uniform string of length $20 \mathrm{m}$ and mass $1 \mathrm{kg}$ is hung vertically. Find the speed of wave at the mid-point of the string :-

A uniform rope of length $10 \mathrm{m}$ and mass $15 \mathrm{kg}$ hangs vertically from a rigid support. A block of mass$5 \mathrm{kg}$ is attached to the free end of the rope. A transverse pulse of wavelength $0.08 \mathrm{m}$ is produced at the lower end of the rope. The wavelength of the pulse when it reaches the top of the rope will be-

Both the strings, shown in figure are made of same material and diameter of $CD$ is double that of $AB$. The pulleys are light. The speed of a transverse wave in the string $AB$ is $v_1$ and in $CD$ it is $v_2,$ then $\frac{v_1}{v_2}$ is :
