transverse wave is found to have a distance of 7.5 cm from a trough
to a crest, a frequency of 12 Hz, and a distance of 7.5 cm from a
crest to the nearest trough. Determine the amplitude, period,
wavelength and speed of such a wave.
The wavelength λ
happens to be the distance between any two nearest identical points
7.5 +7.5 = 15 cm.
The period is reciprocal to the
frequency: T = 1/f = 1/12 s = 0.083 s.
The speed of the wave is v = λ
/ T = 15 cm / (1/12 s) = 180 cm/s.
Finally, from the given data it is
impossible to determine the amplitude (need more data).
