Transverse and Longitudinal waves

What do gravity waves tell us?

What type of wave is a capillary wave?

Swinging the table fan is an example of which type of motion

Define wave motion. Write down the characteristics of wave motion.

The equation of a transverse wave travelling along a string is given by $\mathrm{Y}=2.0 \sin \pi (0.2 \mathrm{x}-2.0\mathrm{t})$, where $\mathrm{y},\mathrm{x}$ are in meters and $t$ is in seconds Find the amplitude, wavelength speed and frequency of the wave.

A person who is sitting at a distance of $400 \mathrm{m}$ from a source of sound is listening to a sound of $500 \mathrm{Hz}$. Find the time period (in seconds) between successive compressions from the source.

The velocity of the sound in a gas is directly proportional to the square root of its _____.

Sound requires a _____ to travel.

The velocity of sound increases with an increase in the temperature of the gas.

The velocity of sound is the least in a gaseous medium.

The velocity of sound is higher in gases than liquids.

The velocity of sound is independent of temperature.

Transverse waves can propagate through solid, liquid and gas.

Compression is the part of a longitudinal wave in which the particles of the medium are closer to one another than they are normally.

In the propagation of a longitudinal wave in a medium, particles vibrate about their mean position in the direction of motion of the wave. 

A point particle is acted upon by a restoring force $-k{x}^3.$ The time period of oscillation is $T$ when the amplitude is $A.$ The time period for an amplitude $2A$ will be:

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.

Assertion: When a wave travels from a denser medium to a rarer medium, its amplitude of oscillation will increase.

Reason: In a rarer medium speed of wave is more.

Assertion: Sound wave bends towards normal in travelling from air to water.

Reason: Whenever a wave travels from a rarer medium to a denser medium, it bends towards normal.
