Practise IB Physics SL C.4.2 by identifying nodes, antinodes, amplitudes and phase relationships along standing waves in strings and pipes.
The solid line represents the standing wave at time t and the dotted line represents the standing wave at an instant later. The dot is the equilibrium position of a particle P in the pipe. The up arrow indicates displacements to the right and the down arrow displacements to the left.
On the diagram, draw
a dot to indicate the approximate position of P at time t,
an arrow to indicate the velocity of P at time t.
