Answer 1

Answer:

Please see the explanation

Explanation:

As we know that standing waves have nodes and anti nodes which is produced by repeated interference of two waves of same frequency in opposite direction in the same medium. In this case when we have a rope attached to a point on a wall, we move the rope in up and down direction we will create waves.

The wave will go up to the wall and then reflect back and thus create an opposite wave. And as we can create a standing wave.
