Question

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.

Answer #1

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

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)

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?

A double-slit experiment uses coherent
light of wavelength 633 nm with a slit separation of 0.100 mm and a
screen placed 2.0 m away.
(a) How wide on the screen is the central bright fringe?
(b) What is the distance on the screen between first-order and
second-order bright fringes?
(c) What is the angular separation (in radians) between the
central maximum and the first-order maximum?

In a double-slit interference experiment, the slit separation is
2.29 μm, the light wavelength is 532 nm, and the separation between
the slits and the screen is 4.42 m. (a) What is
the angle between the center and the third side bright fringe? If
we decrease the light frequency to 94.8% of its initial value,
(b) does the third side bright fringe move along
the screen toward or away from the pattern's center and
(c) how far does it move?

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 double slit interference pattern is created by two narrow slit
spaced 0.025 mm apart on a screen 2 m away from the slits.
a. If the seventh bright fringe on the detector is 10 cm away
from the central fringe, what is the wavelength of light (in nm)
used in this experiment?
b. What is the angle of the diffraction order?

Blue light falling on a double-slit produces interference
fringes on a screen. What will happen to the fringes (closer
together, farther apart, remain the same, or no more fringes) if
The blue light is replaced by red light? The blue light is replaced
by incoherent light? The separation between the slits is decreased?
The distance to the screen is decreased? The entire experiment is
immersed in water?
