A wave travels along a string at a speed of \(\text{1,5}\)
\(\text{m·s$^{-1}$}\). If the frequency of the source of the wave
is \(\text{7,5}\) \(\text{Hz}\), calculate:
the wavelength of the wave
the period of the wave
Solution not yet available
Water waves crash against a seawall around the harbour. Eight waves hit the
seawall in \(\text{5}\) \(\text{s}\). The distance between successive
troughs is \(\text{9}\) \(\text{m}\). The height of the waveform trough
to crest is \(\text{1,5}\) \(\text{m}\).
How many complete waves are indicated in the sketch?
Write down the letters that indicate any TWO points that are:
in phase
out of phase
Represent ONE wavelength.
Calculate the amplitude of the wave.
Show that the period of the wave is \(\text{0,625}\)
\(\text{s}\).
