Two waves, each of frequency 250 Hz and wavelength
25.12 cm, produce
interference in which the maximum amplitude is 0.10 m and minimum
amplitude is
0.04 m. Estimate (a) the angular frequency of each wave, (b) the
propagation
constant (k) of each wave, (c) the amplitude of each wave and (d)
resultant
intensity, if the phase difference between the waves is 3.14
radian.

Two travelling sinosoidal electromagnetic waves, each with an
intensity 15 W/m2W/m2 , interfere to form a standing wave. The
resulting electric field E⃗ (z,t)E→(z,t) has nodes (i.e., is zero
at all times) at z=…,−2a,−a,0,a,2a,…z=…,−2a,−a,0,a,2a,… with aaa =
4.0 mm , and satisifes E⃗ (z,0)=0E→(z,0)=0. Furthermore, the
magnetic field B⃗ (z,t)B→(z,t) is observed to point along ±i^±i^
everywhere. You may take ccc = 3.0×108 m/sm/s and
8.9×10−12 F/mF/m .

Two loudspeakers emit coherent in phase sound waves with at a
frequency of 68.8 Hz. The speed of sound is 344.0 m/s.
Point q is vertically located 2.0 m from the bottom speaker and
5.0 m from the top speaker. At point q, is there maximum
constructive interference, complete destructive interference, or
neither?? Explain your answer.

Two waves traveling in opposite directions on a stretched rope
interfere to give the standing wave described by the following wave
function:
y(x,t) = 4 sin(2πx) cos(120πt),
where, y is in centimetres, x is in meters, and t is in seconds.
The rope is two meters long, L = 2 m, and is fixed at both
ends.
In terms of the oscillation period, T, at which of the following
times would all elements on the string have a zero vertical...
