Question

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.

Answer #1

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

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...

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.

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.

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...

In a double-slit experiment what will happen to the interference
pattern shown on the screen if
a) the wavelength of the light is increased?
b) the distance between the slits is increased?
c) the screen is moved further away from the slits?

In a double-slit experiment, the distance between slits is
0.5.0 mm and the slits are 2.0 m from the screen. Two interference
patterns can be seen on the screen: one due to light of wavelength
480 nm, and the other due to light of wavelength 600 nm. What is
the separation on the screen between the second -order (m
= 3) bright fringes of the two interference patterns?(show the ray
diagrams)

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

Problem about double-slit interference.
a) Choose and state a wavelength in the electromagnetic spectrum
that corresponds to visible light.
b)We would like it to be easy to measure the positions of the
dark and bright fringes so let’s aim for having a distance of 1cm
between adjacent bright fringes. Choose the distance of the screen
and the distance between the slits so that this is the case. The
slit distance should be much bigger than the wavelength, but much
smaller...

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.
