Consider the following wave functions :
(a) y = A sin(ωt - kx)
(b) y = A sin(kx - ωt)
(c) y = A cos(ωt - kx)
(d) y = A cos(kx - ωt)
(e) y = A sin(ωt + kx)
(f) y = A cos(ωt + kx)
Write the equations of reflected wave after reflection from a free and a fixed boundary. Also find the resulting stationary waves formed by the superposition of its reflected wave.
