The wavelength of a travelling wave is 4m at a frequency of 10hertz. what time later will there be another crest at x=3m? ii) if the amplitude of the wave is 12m, write the equation of the wave?
I would write the equation as:
You have everything here:
From the frquency you get the period as:
so finally your wave (propagating in the
A basic wave@ may be expressed in the following general equation
From the given frequency of
(i) What time later will there be another crest at
We know that for any value of
(ii) Inserting values of
@which can be shown to be the usual sine and cosine forms using Euler's formula.
Rewriting the argument as,
We see that this expression describes a vibration of wavelength
