Question

A wave going in a solid
A. Must be longitudinal
B. May be longitudinal
C. Must be transverse
D. May be transverse

Answer 1

Hint: Here in this question, we have to state which wave can travel in the solid medium. Mechanical waves are waves that move through a solid, liquid, or gas with a wave speed that is influenced by the elastic and inertial characteristics of that medium. Mechanical waves can move in either longitudinal waves or transverse waves, which are the two most common wave motions.

Complete step by step solution:
Before starting the solution we must know that a wave is a disturbance in a medium that propagates while transferring energy and momentum with no net motion of the medium. A travelling wave is one whose positions of maximum and minimum amplitude move through the medium.

We are aware that mechanical waves can travel in both transverse and longitudinal directions using a medium of closely spaced particles in a solid. As a result, particles can travel in both the direction i.e, longitudinal and transversal. Therefore, we get that the correct answer is a wave going in a solid may be longitudinal as well as may be transverse.

Hence, the correct options are B and D.

Note: Some special properties of waves are there in which the major ones are, A wave's fundamental characteristics (components) include its frequency, amplitude, wavelength, and speed. How many waves pass a spot in a specific amount of time is measured by frequency. The waves will carry more energy since they will be closer together and at higher frequencies.
