Question

A laser of 632.8 nm is incident on a set of narrow slits, separated by a distance of 0.01 mm. If a screen is 20 cm away, Calculate the ratio of the distance of the 2nd minimum to the first minimum as measured from the central maximum.

Please show work and explain

Answer #1

A red He-Ne laser with a wavelength of 632.8 nm illuminates two
narrow horizontal slits with gap distance 0.200 mm. A pattern of
interference bands then appears on a screen 1.00m from the
columns.
a) How far from the central maximum, in both radians and
millimeters on the screen, is first minimum?
b) How far in millimeters on the screen, is the fifth maximum
from the central maximum?
c) How big is the intensity in the fifth maximum compared to...

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.
b. In a double-slit experiment, the intensity at the peak of the
central...

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.

Two
narrow slits separated by 0.05 mm are illuminated with light =
540 nm. How many bands of bright lines are there between the
central maximum and the 12-cm position? (The distance between the
double slits and the screen is 1 m).

Laser light of an unknown wavelength falls incident on a pair of
slits separated by 25.0 µm. This produces an interference pattern
on a screen 1.80 m away with the first-order bright fringe being
39.7 mm from the center of the central maximum. What is the
wavelength of the laser light?

A pair of narrow, parallel slits separated by 0.300 mm is
illuminated by green light (? = 546.1 nm). The interference pattern
is observed on a screen 1.10 m away from the plane of the parallel
slits.
(a) Calculate the distance from the central maximum to the first
bright region on either side of the central maximum.
________________mm
(b) Calculate the distance between the first and second dark
bands in the interference pattern.

Two narrow slits are illuminated by a laser with a wavelength
of 543 nm. The interference pattern on a screen located x = 4.50 m
away shows that the third-order bright fringe is located y = 7.20
cm away from the central bright fringe. Calculate the distance
between the two slits. ("1st order" means m=1, "second order" means
m=2, etc).
