Practise IB Physics HL C.4.1 by solving standing-wave formation problems using reflection, superposition and boundary conditions.
A loudspeaker emits sound of frequency 210 Hz into a pipe with one open and one closed end. The diagram shows a representation of the standing wave established in the pipe.

The length of the pipe is 1.20 m .
Outline how the standing wave is formed in the pipe.
The incoming wave is reflected «from the closed end»
<<The reflected and incoming wave>> superpose/interfere
