Classification of Waves

An electromagnetic wave is travelling in a medium with a velocity $\overrightarrow{v}=v\widehat{i}$ . The electric field oscillations, of this electromagnetic wave wave, are along the y – axis.

(a) Identify the direction in which the magnetic field oscillations are taking place, of the electromagnetic wave wave.

(b) How are the magnitudes of the electric and magnetic fields in the electromagnetic wave related to each other?

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

Which of the following are mechanical waves?

In seismology, the $S$ wave is a transverse wave. As an $S$ wave travels through the Earth, the relative motion between the $S$ wave and the particle is

Suppose that the electric field part of an electromagnetic wave in vacuum is

$E=(3.1 \mathrm{N} {\mathrm{C}}^{-1})\cos \left[\right(1.8 \mathrm{rad} {\mathrm{m}}^{-1})y+(5.47\mathrm{times};106 \mathrm{rad} {\mathrm{s}}^{-1}\left)t\right]$

What is the wavelength $\lambda$?

Which of the following has the longest wavelength?

Long distance short wave radio broadcasting uses?

An antenna behaves as resonant circuit only when its length is

AM is used for broadcasting because 

In an amplitude modulated wave for audio frequency of $500$ $\mathrm{cycles} {\mathrm{s}}^{-1}$ the appropriate carrier frequency will be -

The maximum range of ground of surface wave propagation depends on-

The radio waves of frequency $300 \mathrm{MHz}$ to $3000 \mathrm{MHz}$ belongs to -

The frequencies of electromagnetic waves employed in space communication vary over a range of -

In amplitude modulation, carrier wave frequencies are:

Two light boats are $10 \mathrm{m}$ apart on a lake. When one boat is at its highest point, the other boat is at its lowest point due to popping. Each boat pops up and down with a period of $4.0$$\mathrm{s}$ due to wave motion on the surface of water. Both boats are always within a single cycle of the waves. Then find the speed of the waves in $\mathrm{m} {\mathrm{s}}^{-1}$.

Which of the following statement is not true about matter waves?

Assertion: In the equation $y=A\sin \left(kx-\omega t\right)$ particle at $x=0$ starts from its mean position towards the negative $y$-axis.

Reason: The wave corresponding to the given equation is travelling towards the positive $x$-direction.

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.
