Question

Two
light sources emit waves that are in phase with a wavelength of λ =
350 nm. The two waves meet at a distant point where Wave #1 has
traveled 100 nm. The distance traveled by Wave #2 is variable.
Which of the distances for Wave #2, listed below, would result in
constructive interference?

Answer #1

Two in-phase sources of waves are separated by a distance of
3.68 m. These sources produce identical waves that have a
wavelength of 5.28 m. On the line between them, there are two
places at which the same type of interference occurs. (a) Is it
constructive or destructive interference? (b) and (c) Where are
these places located (the smaller distance should be the answer to
(b))?

Two in-phase sources of waves are separated by a distance of
3.88 m. These sources produce identical waves that have a
wavelength of 5.65 m. On the line between them, there are two
places at which the same type of interference occurs.
(a) Is it constructive or destructive
interference? (b) and (c) Where
are these places located (the smaller distance should be the answer
to (b))?

Two sound sources emit sound of wavelength 1.4m in phase. One
source is at 4.9m i^ and the other is at -4.9m hati.
An observer is at r⃗ =6.8mj^, a location of constructive
interference, and walks to r⃗ =13.6mi^+9.4mj^.
In this process how many times did the observer encounter a
location of destructive interference (in other words a quiet
location)?
Answer:

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...

Waves from two slits are in phase at the slits and travel to a
distant screen to produce the
second minimum of the interference pattern. The difference in the
distance traveled by the
waves is:
A. half a wavelength
B. a wavelength
C. three halves of a wavelength
D. two wavelengths
E. five halves of a wavelength
why A is wrong and show me the steps of the correct one

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.

1. (a) Two point sources are generating periodic waves in phase.
A point on the fourth nodal line is 25.0cm from the source and
39.0cm from the farthest source. Construct a sketcth of the
physical situation and determine the wavelength.
(b) Two point sources, 3.0cm apart,are generating periodic waves
in phase. A point on the third antinodal line of the wave pattern
is 10cm from one source and 8.0cm from the other source. construct
a sketch of the physical situation...

In wave interference theory, how would we explain an
illustration of two wave sources separated by distance, d,
and an observation point, P, a discussion of the difference in
distances, Δ, between the two wave sources and point P, and the
constructive interference that results at P if .

1. Which of the following is not a condition for constructive
interference when light waves from two sources meet at a point?
a. the path difference is one wavelength
b. the intensity is maximum
c. a bright fringe is formed
d. a crest meets a crest
e. All of the choices are conditions for constructive
interference
2. Coherent light of wavelength 500 nm is incident on two
parallel slits separated by 0.08 mm. On a very distant and large
screen,...

1. [ ] Constructive interference occurs when two or more waves
overlap and the amplitude of the resultant wave is greater than
that of any individualwaves.2. [ ] In Young’s double-slit
experiment, the condition for constructive interference is that the
path difference of two waves must be either zero or some integer
multiple of the wavelength.3. [ ] When a light wave traveling from
air is reflected on a diamond surface, the reflected wave...
