Question

explained about stationary waves in open Pipe and closed pipe​

Answer 1

Explanation:

If the waves with some frequency are sent through the closed pipe, the waves gets reflects from closed end. When the incident and reflected waves with same frequency and in opposite direction superimposed the stationary waves formed in the closed pipe.

Answer 2

Answer:

Resonance increases the amplitude of the vibrations, which can form standing waves in the tube. The length of the air column determines the resonant frequencies. Open and closed ends reflect waves differently. The closed end of a tube is an antinode in the pressure (or a node in the longitudinal displacement).
