Question

How can transverse waves be produced on a rope?

Answer 1

Hint :Waves can be defined as oscillations or disturbances that travel through a medium and transfer energy from one place to another. Hence, to create transverse waves in a rope, we need to create a disturbance in the rope.

Complete Step By Step Answer:
Waves can be defined as an oscillation or a disturbance of the medium that travels through space also providing transfer of energy with the oscillations, with mostly no permanent displacement of the particles of the medium
There are two types of waves - Transverse waves and Longitudinal waves
Transverse waves are waves that oscillate in a plane perpendicular to the direction of propagation. Light waves are an example of transverse waves. The wave propagates in the form of crest and trough.
Longitudinal waves are waves that oscillate in a plane parallel to the direction of propagation of waves. Sound waves are an example of longitudinal waves. The wave propagates in the form of compressions and rarefactions.
For a transverse wave, the crest is known as the maximum displacement in the positive direction, and the trough is known as the maximum displacement in the negative direction.
Hence, if a wave is moving with vertical oscillations, the topmost position of the wave is known as crest and the bottommost position is known as the trough.
Now, let us consider a rope that is tightly tied on a vertical wall and is held horizontally parallel to the floor.
Now, to generate transverse waves in the rope, the plane of oscillations should be perpendicular to the rope. Any vertical or horizontal or inclined planes are considered perpendicular planes to the rope.
As a transverse wave contains alternate crests and troughs, we can generate a transverse wave in a rope in a vertical plane by moving the rope up and down alternately.

Note :
Transverse waves in a rope can be generated by oscillating the rope in any direction other than up and down. The only requirement is that the oscillation should be perpendicular to the rope. Hence, we cannot move the rope forward and backward as it is in the direction of the rope.
