Question

Blue light (λ = 450 nm) is used in a double slit experiment. The
light passes through

a diffraction grating with 1250 lines per centimeter, and the light
is projected onto a

screen, which is 1.75 m from the slits. What is the distance from
the central bright spot

to the third order maximum? What is the distance from the central
bright spot to the

second order minimum?

Answer #1

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...

You shine blue light (400 nm) and red light (700 nm) onto a
Young’s double slit apparatus with a slit separation distance of
6.00 μm. In order, what are the colors of the first five bright
fringes from the central bright spot?

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...

a) A double slit experiment is with 450 nm light and two narrow
slits which are 0.5 mm apart. At what angle to the straight through
beam will be one observe:
i. the third order bright fringe.
ii. the second minimum from the central maximum.
b) By drawing appropriate diagrams, show the differences between
intensity or pattern for double slits intereference and single slit
diffration

It is found that when blue light, λ = 470 nm, passes through a
diffraction grating with a slit separation d, the
diffraction pattern has a third order maximum at
an angle θ = 44.8o. At what angle will red
light, λ = 660 nm, have it's second order maximum
when passed through the same diffraction grating.
A.
29.4o
B.
39.7o
C.
41.3o
D.
31.6o

In a double-slit experiment, light with a wavelength λ passes
through a double-slit and forms an interference pattern on the
screen at a distance L from the slits. What statement is true for
the resulting interference pattern if the frequency of the light
increases?
The distance between maxima increases.
Not enough information given.
The distance between maxima stays the same.
The distance between maxima decreases.

Light with a wavelength of 633 nm passes through a slit 6.38
?m wide and falls on a screen 1.60 m away. Find the
distance on the screen from the central bright fringe to the third
dark fringe above it. ___ cm
Monochromatic light passes through two slits separated by a
distance of 0.0332 mm. If the angle to the third maximum above the
central fringe is 3.21 degrees, what is the wavelength of the
light? __ nm

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 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

Consider a source of light with wavelength λ = 490 nm
that shines on two identical narrow slits. The slits are separated
by a distance a = 30 μm. An interference pattern
is observed on a screen located a distance L away from the
slits. On the screen, the location of the second dark spot to the
left of the central bright spot is found to be y = 1.2 cm
from the central bright spot. Let this particular position...
