As a function of position and time, a transverse wave of wavelength l travelling

Question

As a function of position and time, a transverse wave of wavelength l travelling along the x axis
can be described by the equation:
y(x, t) = Acos(kx?wt)
(a) Explain what each of the quantities A, k and w in this equation are. Also specify the direction
in which the wave is travelling. [5]
(b) A second wave is travelling along the x axis, and it only differs from the above wave in that
the argument of the cosine is (kx?wt +f). What does f represent? What values can f take
if the two waves are to interfere (i) constructively, (ii) destructively? [2]
(c) A Young

Explanation / Answer

(a). a= amplitude of the particle doing shm in wave.K is wave number,w is the angular velocity.the wave is moving in +ve x direction b.f represent the phase difference between two waves
