The waves emitted from a source A is given by
y1 = 6 sin π(20t – 0.5x)
where y1, x and t are expressed in units of meter and seconds.
(a) Determine the wavelength and the frequency of the radio waves. At the same time,
source B generates waves y2 that is identical to y1 except that there is a phase
difference of π/3
(b) Write down the wave equation for y2
If y2 were superimposed to y1
(c) what is the phase constant and the amplitude of the resultant wave?
(d) write down the equation of the resultant waves.
