Question

1. A 680 nm laser illuminates a double slit apparatus with a slit separation distance of 7.83 μm. On the viewing screen, you measure the distance from the central bright fringe to the 2nd bright fringe to be 88.2 cm. How far away (in meters) is the viewing screen from the double slits?

2. A 600 nm laser illuminates a double slit apparatus with a slit separation distance of 3.55 μm. The viewing screen is 1.50 meters behind the double slits. What is the distance (in meters) from the central bright fringe to the 3nd dark fringe?

Answer #1

A 600 nm laser illuminates a double slit apparatus with a slit
separation distance of 3.55 μm. The viewing screen is 1.50 meters
behind the double slits. What is the distance (in meters) from the
central bright fringe to the 3nd dark fringe?

A 600 nm laser illuminates a double slit apparatus with a slit
separation distance of 3.55 μm. The viewing screen is 1.50 meters
behind the double slits. What is the distance (in cm) between the
2nd and 3rd dark fringes?

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?

A laser beam with a wavelength of 490 nm passes through a
double-slits with a separation of 0.04 mm and falls on a screen 60
cm behind the slits. (a) Find the positions of the 1 st and 2nd
order bright fringes respected to the center on the screen. (b)
Find the position of the 1 st -order dark fringe respected to the
center on the screen.

1. A double slit apparatus is held 1.2 m from a screen. Red
light (λ = 600.0nm) is sent through the double slit and the
interference pattern on the screen shows a distance of 12.5cm
between the central fringe and tenth order bright fringe. What is
the separation of the slits?

A Young’s double-slit apparatus is illuminated with 669 nm light
and the screen is positioned 2.2 m from the double slits. If the
spacing between the two slits is 0.33 mm …
Part a) What is the angle from the center line (the line from
the center of the two slits to the central bright spot) to the
second order bright spot?
Part b) What is the distance from the zeroth order bright fringe
and on the screen to the...

In a Young's double-slit experiment, a set of parallel slits
with a separation of 0.104 mm is illuminated by
light having a wavelength of 566 nm and the
interference pattern observed on a screen 3.50 m
from the slits.
(a) What is the difference in path lengths from the two slits to
the location of a fifth order bright fringe on the
screen?

In a Young's double-slit experiment, a set of parallel slits
with a separation of 0.150 mm is illuminated by light having a
wavelength of 600 nm and the interference pattern observed on a
screen 4.50 m from the slits.
(a) What is the difference in path lengths from the two slits to
the location of a fifth order bright fringe on the screen? μm

the location of...

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.

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...
