Question

A double-slit experiment produces an interference pattern on a screen 2.8 m m away from slits. Light of wavelength λ= 520 nm n m falls on the slits from a distant source. The distance between adjacent bright fringes is 7.2 mm m m . Part A Find the distance between the two slits. Express your answer using three significant figures. Part B Determine the distance to the 5th order dark fringe from the central fringe. Express your answer using three significant figures.

A double slit experiment produces an interference pattern on a
screen 2.8 m away from the slits. Light of wavelength = 480 nm
falls on the slits from a distant source. The distance between
adjacent bright fringes is 5.8 mm.
a) find the distance between the two slits. Express your answer
using 3 significant figures.
b) determine the distance to the 6th order dark fringe from the
central fringe. Express your answer using three significant
figures.

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

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...

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 physics instructor wants to produce a double-slit interference
pattern large enough for her class to see. For the size of the
room, she decides that the distance between successive bright
fringes on the screen should be at least 2.80 cm.
If the slits have a separation d=0.0200mm, what is the
minimum distance from the slits to the screen when 632.8-nm light
from a He-Ne laser is used?
Express your answer to three significant figures.

A physics instructor wants to produce a double-slit interference
pattern large enough for her class to see. For the size of the
room, she decides that the distance between successive bright
fringes on the screen should be at least 3.00 cmcm.
If the slits have a separation d=0.0155mmd=0.0155mm, what is the
minimum distance from the slits to the screen when 632.8-nmnm light
from a He-Ne laser is used?
Express your answer to three significant figures. Units of

In a
double-slit interference pattern, light from the top slit travels a
distance of 4.0 m between the slit and a point on the screen. How
far does light from the bottom slit travel to that point
if
there is a bright fringe at that point? What about if there is a
dark fringe at that point?
Choose from this
list:
A. 4.0 m +
2.2λ
B. 4.0 m +
3.5λ
C. 4.0 m +
3.8λ
D. 4.0 m +...

A double slit interference experiment is submerged in alcohol (n
= 1.3736). On the detecting screen the distance between the zeroth
and first order bright fringes is 1.52 cm. The distance to the
screen from the slits is 2.7225 meters. The light has a wavelength
in air of 615.6 nm. Find the distance between the slits.

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...

A viewing screen is separated from a double-slit source by 1.7m.
The distance between the two slits is 0.035mm. The second order
bright fringe (m=2) is 5.1cm from the center line.
(a) Determine the wavelength of the light.
(b) Calculate the distance between adjacent bright fringes.
