State the type of wave for which the oscillations are perpendicular to the direction of energy transfer.
State two objects that can be used in the classroom to demonstrate wave motion.
Fig. 1.1 shows a waveform consisting of compressions and rarefactions.
Fig. 1.1
Annotate the diagram to show one complete wavelength, and label it λ.
The compression wave in Fig. 1.1 is a progressive wave in which 5 compressions pass a fixed point every 2 seconds.
Determine the frequency of the wave.
