Question

Identify the type of waves shown below.

                                (A)

                                (B)
i).Mark the region of compression and rarefaction in A
ii).Mark crest and trough in B.
iii).State the direction of wave A with respect to the direction of vibrating particles.

Answer 1

Hint: The wave is described as the disturbance in the medium.
This varies from every point at each time.
Because of the oscillating, the energy can travel over a large distance.

Complete step by step answer:
The initial energy is given as an input for a mechanical wave. Once when we applied this initial energy the wave can be passed through the medium till the energy gets transferred completely. The sound wave is also referred to as the mechanical wave.
Generally, the sound waves are also called a mechanical wave because it requires a medium to travel. When the wave travels through the air, the sound waves travel in the form of pressure variations. Hence the compression is referred to as the high-pressure region and rarefaction are referred to as the low-pressure region.
In the above-given diagram, the wave is moving in a positive direction.
Some other kinds of waves are known as electromagnetic waves and this electromagnetic wave does not require any physical medium to travel they can travel vacuum.

i).In the above diagram, it is marked as the compression and rarefaction.
It is the positive peak of the wave and there exits maximum amplitude is known as the crest. The trough is referred to as the negative peak of the wave where the minimum amplitude exits.

In the given diagram the wave traveled in a positive direction.

Note:
The capillary waves are the small ripples it travels along the phase boundary of the fluid
here the phase velocity gets dominated by the surface tension.
Generally, the gravity waves having longer wavelengths here the gravity resisting the upward displacement of fluid.
