Question

A physics student demonstrates Young's double-slit experiment using 632.8 nm light from a HeNe laser. The laser light passes through two narrowly separated slits that have a spacing of d. The light produces an interference pattern on a screen that is 4.20 meters in front of the slits. The spacing between the m=2 and m=3 maxima as seen on the screen is 12.0 cm.

Determine the spacing between the slits.

For the situation described above, determine the phase difference between the rays from the two slits arriving at a position 18.0 cm above the central maximum. Describe the intensity of light at this position as a fraction of the maximum intensity Imax on the screen.

Answer #1

In Young's double-slit experiment, 632.8 nm light from a HeNe
laser passes through the two slits and is projected on a screen. As
expected, a central maximum (constructive interference) is observed
at the center point on the screen. Now, a very thin piece of
plastic with an index of refraction n=1.48 covers one of the the
slits such that the center point on the screen, instead of being a
maximum, is dark.

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.

light and a distance of 2.00 m between the slits and the screen.
The tenth interference minimum is observed 7.90 mm from the central
maximum. Determine the spacing of the slits (in mm).
(b) What are the smallest and largest wavelengths of visible
light that will also produce interference minima at this
location?

Find the wavelength of the laser through two slits. The distance
between the slit to the screen is 1 meter, the two slits are
separated by 0.01 mm, and the distance between interference maxima
is 6.33 cm. The angle is also 3.63 degrees between the first maxima
(center) and the second maxima, with an order of m =1. What color
laser is this, and does your answer match up with the wavelength of
a HeNe laser?

A double- slit experiment is performed with a coherent (single
frequency/wavelength) beam of laser light.
1, suppose that the two slits are separated by a distance D= 0.1
mm; the distance (H) between the center of the pattern and the
second ( m=2) bright region is 1.0 cm; and the distance(L) between
the screen and the slits is 1.0 m. use the results of this
experiment to determine the wavelength of the light.

1. a. Light of wavelength 694.3 nm from a ruby laser is incident
on two narrow parallel slits cut in a thin sheet of metal. The
slits are separated by a distance of 0.088 mm. A screen is placed
1.5 m beyond the slits. Find the intensity, relative to the central
maximum, at a point on the screen 1.4 cm to one side of the central
maximum.

In a double-slit experiment, light with a wavelength λ passes
through a double-slit and forms an interference pattern on the
screen at a distance L from the slits. What statement is true for
the resulting interference pattern if the frequency of the light
increases?
The distance between maxima increases.
Not enough information given.
The distance between maxima stays the same.
The distance between maxima decreases.

You are doing a double slit experiment with light. One slit is
wider than the other, so one of the waves is stronger. There is
never exact cancellation, or complete destructive interference. On
a screen far away you observe a pattern of maxima and minima, and
the intensity of the light in a maximum is 4 times as large as that
in a minimum. What is the ratio of the widths of the two slits?

Constants
Laser light of wavelength 632.8 nm falls normally on a slit that
is 0.0260 mm wide. The transmitted light is viewed on a distant
screen where the intensity at the center of the central bright
fringe is 8.40 W/m^2.
