A Kundt’s tube apparatus has a copper rod of length 1.0 m clamped at 25 cm from one of the ends. The tube contains air in which the speed of sound is 340 m/s. The powder collects in heaps separated by a distance of 50 cm. Find the speed of sound waves in copper.

Given:
Speed of sound in air


Velocity of sound in Kundts tube



Length at which copper rod is clamped


Distance between the heaps:





On substituting the respective values in the above equation, we get:
