**I
will be glad to see your comment if you have any query and thumb up
if you are satisfied. Thanks !**

Find a mathematical expression to describe what happens when two
traveling sound waves of nearly the same wavenumber k and angular
frequency ? are superimposed. Use the complex form to add the two
waves.What is the frequency of the resulting wave? What is the beat
frequency? At what velocity do the beats travel?

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.

K 2. Point Source Interference Pattern
Consider a two-dimensional x-y space in which there are two
identical and synchronized point sources located at y=±D/2 emitting
waves of wavelength λ. The sources are said to constructively
interfere at any location if the phase difference between waves
received from the two sources at that location differ by an
integral multiple of 2π. Equivalently, the distances from the
location to the two sources differ by an integral number of
wavelengths. Derive the complete...

Two waves traveling together along the same line are given
by
E1=4.00cos(π/4-ωt)
and E2=5.00cos(π-ωt) , each
with the same angular frequency. Write the form of the resultant
wave ER due to the superposition of the two
waves. You’ll need to find ER’s amplitude and
phase angle.

Two traveling waves with the same amplitude A, frequency f, and
wavelength λ, but out of phase with each other by one quarter of a
wavelength, are both traveling to the right and superpose in space.
Find the amplitude, wavelength, and frequency of the resulting wave
in terms of the given symbols. Write the equation of the resulting
traveling wave y ( x , t ).

The wave functions of two waves traveling in the same
direction are given below. The two waves have the same frequency,
wavelength, and amplitude, but they differ in their phase
constant.
y1 (x,t) = 2 sin(2πx ‒ 20πt), and
y2 (x,t) = 2 sin(2πx ‒ 20πt + φ),
a)where, y is in centimetres, x is in meters, and t is
in seconds.
Which of the following wave functions represents the
resultant wave due to the interference between the two waves:...

(1A) A vertical spring with a spring constant of 8 N/m and
damping constant of 0.05 kg/s has a 2 kg mass suspended from it. A
harmonic driving force given by F = 2 cos(1.5 t ) is applied to the
mass. What is the natural angular frequency of oscillation of the
mass? What is the amplitude of the oscillations at steady state?
Does this amplitude decrease with time due to the damping? Why or
why not?
(1B) Two traveling...

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...

PART A
Two light waves of the same frequency start out in phase (with
amplitudes going up at the same moment), and they interfere having
traveled different distances. What happens if the path
difference in the two waves is 1200 nm and the wavelength of the
light is 400 nm (blue light)?
The waves add in step and the time-averaged power at
that place is 4x that of one wave alone.
The waves add in step and the time-averaged power at
that is...

m apart. If the tension in the cord is 140 N, how long will it take

2. A 50.0 Kg ball hangs from a steel wire 1.00 mm in diameter
