Question

a) A double slit experiment is with 450 nm light and two narrow slits which are 0.5 mm apart. At what angle to the straight through beam will be one observe:

i. the third order bright fringe.

ii. the second minimum from the central maximum.

b) By drawing appropriate diagrams, show the differences between intensity or pattern for double slits intereference and single slit diffration

Answer #1

**Solution**

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?

Blue light (λ = 450 nm) is used in a double slit experiment with
the slits separated
by d = 2.10 × 10^-4 m. The distance between the third order bright
fringe and the
central bright fringe is 1.93 × 10^-2 m.
(a) (3 pts.) Determine the distance between the double slit and the
screen.
(b) (3 pts.) Calculate the width of the central bright fringe, i.e.
the separation of
the two zeroth order dark fringes.
(c) (3 pts.) The...

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...

In a double-slit experiment, the second-order bright fringe is
observed at an angle of 0.51°. If the slit separation is 0.11 mm,
then what is the wavelength of the light?
_____???
Two narrow slits are illuminated by a laser with a wavelength of
514 nm. The interference pattern on a screen located x = 4.60 m
away shows that the third-order bright fringe is located y = 9.00
cm away from the central bright fringe. Calculate the distance
between the...

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?

Blue light (λ = 450 nm) is used in a double slit experiment. The
light passes through
a diffraction grating with 1250 lines per centimeter, and the light
is projected onto a
screen, which is 1.75 m from the slits. What is the distance from
the central bright spot
to the third order maximum? What is the distance from the central
bright spot to the
second order minimum?

In a Young's double-slit experiment, light of wavelength
? is sent through the slits. The intensity I at
angle ?0 from the central bright fringe is
lower than the maximum intensity Imax on the
screen. Find an expression for the spacing between the slits in
terms of ?, ?0, I, and
Imax.

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

Light of wavelength 550 nm is used in a double-slit interference
experiment in which the slits are 0.06 mm wide, 0.15 mm apart, and
2.0 m from a screen. At what angle is the third-order diffraction
minimum found?
a) 0.63°
b) 0.74°
c) 1.84°
d) 1.58°

In the double-slit experiment, Michelle strongly believes the
slit separation printed by factory is wrong and it should read 2.0
mm. She placed a screen 2.0m from the slits. Vincent illuminates
the slits with two lasers one with wavelengths of700 nm and the
other of 450 nm simultaneously. At what distance from the central
maximum on the screen will a bright fringe from one pattern first
coincide with a bright fringe from the other?
