Question

a string is fixed at both ends with rigid support. By showing nodes and anti-nodes. draw the figure of first Overtone of oscillation of the string.
​

Answer 1

Answer:

At position of nodes the amplitude is minimum while at position of antinode the amplitude is maximum

Explanation:

As we know that when a travelling wave superimpose with its own reflected wave then due to superposition of two wave wave in the medium it forms loops in the string

This formation of loops is known as standing waves

so in first overtone we have three nodes : Two at the ends of the string and one at mid point of the string.

At the position of node the string will not oscillate and at position of antinode the amplitude of the string is maximum

So we have
