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...

Standing Waves
1. Draw a sine wave. On this graph, indicate what the Amplitude
and Period are. If someone just gave you this graph, how could you
find the Frequency?
2. Imagine that two water waves moving in opposite directions
run into each other. What will the resulting wave look like?
3. When 2 waves interfere, can the resulting wave have a larger
amplitude than either of the two original waves? When?
4. What is the definition of a node?...

What is the wavelength, λ, of a resulting wave of two
co-propagating waves with λ1, λ2, that have the same frequency and
the same amplitude?

Two speakers, facing each other, produce coherent sound waves
that interfere destructively at a point that is ¾ of the way from
one speaker to the other. If the speed of sound is 343 m/s, and the
sound waves are emitted in phase at 880 Hz, which of the following
is a possible distance between the two speakers?
a. 2.3 m b. 0.58 m c. 1.56 m d. 77 cm e. 2.7 m

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 .
A) What is the wavelength λλlambda of the two constituent
travelling waves?...
