Describe what is meant by an acoustic standing wave. Be sure to
include conditions for resonance (Describing what is happening
mathematically or graphically can be helpful)
Homework Answers
A standing wave is essentially a stationary wave, who amplitude is constant for a particular time. Some of the particle on this wave does not move while some points move with maximum amplitude. The point which remains fixed are called Node and one with maximum amplitude is called Anti-Node.
Let us consider two waves in same phase, with same amplitude A,
angular frequency 
and wavelength
, moving in
opposite direction
By superposition, the standing wave is given by
we see that displacement y is zero for
This are the Nodes.
Displacement is maximum for
This are the Anti-nodes.

Question 3 An electromagnetic wave is coupled into a ring resonator. The resonance condition of the ring is that ma-nL, where m is an integer, λ is the wavelength, n is the refractive index of the medium and L is the geometrical length of the resonator path. a) If the resonator is made of glass, n = 1.46, and has a radius of 50pm, calculate the wavelengths of radiation that would meet the resonance condition for m =295 and m=296...
