Question

what is kundt's experiment????

Answer 1

Kundt's tube is an experimental acoustical apparatus invented in 1866 by German physicist August Kundt[1][2] for the measurement of the speed of sound in a gas or a solid rod. The experiment is still taught today due to its ability to demonstrate longitudinal waves in a gas (which can often be difficult to visualise). It is used today only for demonstrating standing waves and acoustical forces.
