Question

Two slits are separated by 0.320 mm. A beam of 482.0 nm light strikes the slits, producing an interference pattern on a screen. The screen is located 2.30 m from the slits. Find the distance from the first dark fringe on one side of the central maximum to the second dark fringe on the other side.

**Please write clearly and legibly!**

Answer #1

Orange light with ? = 615 nm strikes a pair of slits
separated by 0.620 mm .
Part A: On a screen 1.40 m away, what's the distance between the
central maximum and one of the fourth dark fringes?
Part B: On a screen 1.40 m away, what's the distance between the
third bright fringe on one side of the central maximum and the
third dark fringe on the other?
Express your answer with the appropriate units.

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.

(b) Calculate the distance between the first and second dark
bands in the interference pattern.

A two-slit arrangement with 60.3 mm separation between the slits
is illuminated with 491.0 nm coherent light. If a viewing screen is
located 4 m from the slits, find the distance from the first dark
fringe on one side of the central maximum to the second dark fringe
on the other side.

Coherent light (600 nm) passes through two narrow slits
separated by 0.04 mm. An interference pattern is observed on a
screen at a distance 1.50 m away. (a) What is the vertical distance
of the second maximum (not counting the central maximum) from the
center of the interference pattern? (b) At what distance from the
center does the intensity fall to 1/4th of the intensity at the
center?

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.

Light from a laser with a wavelength of 5.60 ✕ 102 nm
is incident on (and perpendicular to) a pair of slits separated by
0.320 mm. An interference pattern is formed on a screen 1.90 m from
the slits. Find the distance (in mm) between the first and second
dark fringes of the interference pattern (in mm)?

A pair of slits, separated by 0.1 mm, is illuminated by light
having a wavelength of 500 nm. An interference pattern is observed
on a screen 1.20 m from the slits. (a) Draw the diagram of the
double slits and determine how far apart will adjacent bright
interference fringes on the screen? (b) What are the angles of the
first and second order fringes with respect to the zeroth order
fringe? (c) Determine the position of the first and second...

Double-Slit Interference
A pair of slits, separated by 0.120 mm, is illuminated by light
of wavelength 643 nm. An interference pattern is observed on a
screen 112 cm from the slits. Consider a point on the screen
located at y = 2.10 cm from the central maximum of the pattern…
a) What is the path difference (in nm) for the two slits at
location y?
b) What is the path difference in waves?
c) Is this a maximum, a minimum...

A beam of electrons hits a pair of slits spaced a distance d
apart (center-to-center). The wavelength of the electrons is 23.8
nm. After traveling through the slits, the electrons form an
interference pattern on a screen located a distance 0.750 m from
the slits. If the center of the second 'bright' fringe occurs 2.30
cm from the center of the central bright fringe on the screen, what
is the separation, d, between the slits?
How fast are the electrons...

A green laser beam (550 nm) strikes a grating and creates an
interference pattern on a wall 2.0 m away. The first maximum
(fringe #1) occurs 11.0 cm from the middle of the central maximum.
(a) Determine the distance between successive slits and the number
of slits per mm. (b) Now a red laser (630 nm) replaces the green.
On which side of the green fringe will the first red fringe appear
– closer to the central maximum or further...
