Resonance in Stretched Strings

The video tutorial explains the phenomenon of resonance in a stretched string. It outlines the objective to determine the frequency of a tuning fork using resonance. The required apparatus includes a sonometer, tuning forks, and other tools. The theory section describes resonance as a sound phenomenon where a body vibrates with increased amplitude when an external force matches its natural frequency. The procedure involves setting up the apparatus, adjusting the string length, and observing resonance conditions. The conclusion summarizes the experiment's findings on the tuning fork's frequency.

What is the main objective of the experiment on resonance in a stretched string?

• By changing the material of the string

• By heating the string

What indicates that resonance has been achieved in the experiment?

• The string changes color

• The paper rider falls off the string

• The tuning fork stops vibrating
