Consider where the wave might appear still.
What is a standing wave?
Think about how waves interact at boundaries.
True or False: Nodes are points of maximum displacement in a standing wave.
Consider the definitions of nodes and antinodes.
Determine the fundamental frequency of a string fixed at both ends with a length of 2 meters and wave speed of 340 m/s.
Use the relationship that connects wave speed, string length and frequency.
A pipe open at both ends produces a fundamental frequency of 440 Hz. Calculate the speed of sound in the pipe if the length of the pipe is 0.5 meters.
Relate frequency and wavelength with the length of the pipe.
