Question

Two narrow slits are used to produce a double-slit interference
pattern with monochromatic light. The slits are separated by 8 mm,
and the interference pattern is projected onto a screen 7 m away
from the slits. The central bright fringe is at a certain spot on
the screen. Using a ruler with one end placed at the central
fringe, you move along the ruler passing by two more bright fringes
and find that the next bright fringe is 23.5 mm away from the
central fringe. What is the wavelength of the light?

Answer #1

A double slit interference pattern is created by two narrow slit
spaced 0.025 mm apart on a screen 2 m away from the slits.
a. If the seventh bright fringe on the detector is 10 cm away
from the central fringe, what is the wavelength of light (in nm)
used in this experiment?
b. What is the angle of the diffraction order?

A double-slit experiment produces an interference pattern on a
screen 2.8 m away from slits. Light of wavelength λ= 460 nm falls
on the slits from a distant source. The distance between adjacent
bright fringes is 6.2 mm.
A) Find the distance between the two slits
B) Determine the distance to the 6th order dark fringe from the
central fringe

Monochromatic light of wavelength λ1 is sent
through two closely-spaced slits separated by a distance
d1 = 1.8 mm. A resulting interference pattern
is shown on a screen L1 away. Another
monochromatic light source, this one of wavelength
λ2, is sent through a diffraction grating
toward the same screen, resulting in a second interference pattern.
The diffraction grating is a distance L2 from
the screen and has 400 lines per mm etched onto it.
A) Assume that L1 = L2...

A double-slit interference pattern is created by two narrow
slits spaced 0.21 mm apart. The distance between the first and the
fifth minimum on a screen 61 cm behind the slits is 6.2 mm. a. Draw
an intensity graph showing the interference pattern and identifying
the central maximum, first minimum, fifth minimum, and the distance
given in the problem declaration. b. What is the wavelength (in nm)
of the light used in this experiment?

A double slit experiment produces an interference pattern on a
screen 2.8 m away from the slits. Light of wavelength = 480 nm
falls on the slits from a distant source. The distance between
adjacent bright fringes is 5.8 mm.
a) find the distance between the two slits. Express your answer
using 3 significant figures.
b) determine the distance to the 6th order dark fringe from the
central fringe. Express your answer using three significant
figures.

Two narrow slits are illuminated by a laser with a wavelength of
578 nm. The interference pattern on a screen located x = 4.50 m
away shows that the third-order bright fringe is located y = 9.10
cm away from the central bright fringe. Calculate the distance
between the two slits.
First you have to calculate the angle of the maximum. Then you
can use the formula for bright fringes of double slits.

With a monochromatic light of wavelength ?? = 532 nm A
double-slit interference pattern is produced on a screen as shown
in the picture. The slit separation ?? is 0.10 mm, and the
slit–screen separation ?? is 50 cm. Assume that the angle θ (from
the slit center to the maxima and minima) small enough to permit
use of the approximations sin θ ≈ tan θ ≈ θ, in which θ is
expressed in radian measure.

A monochromatic light with wavelength 480.0 nm strikes a
pair of narrow slits with spacing
0.100 mm. The first dark fringe is formed on a screen at
a vertical distance of 1.20 cm from the center of a screen placed
in front of the slit.
