Show that a standing wave created by two unequal-amplitude waves

E1 = E, sin (kx + wt)

and

ER = pE, sin (kx ± wt)

has the form

E1 = E, sin (kx + wt) ER = pE, sin (kx

Here ρ is the ratio of the amplitude reflected to the amplitude incident. Discuss the meaning of the two terms. What happens when ρ = 1?

E1 = E, sin (kx + wt) ER = pE, sin (kx wt)
