Question

In a double-slit experiment, the second-order bright fringe is observed at an angle of 0.51°. If the slit separation is 0.11 mm, then what is the wavelength of the light?

_____???

Two narrow slits are illuminated by a laser with a wavelength of 514 nm. The interference pattern on a screen located x = 4.60 m away shows that the third-order bright fringe is located y = 9.00 cm away from the central bright fringe. Calculate the distance between the two slits.

_____???

The screen is now moved 1.1 m further away. What is the new distance between the central and the third-order bright fringe?

_____???

Help me please and show work! Thanks!

The solution for this question is given below

The answer is corrected.

Please give a thumbs up if you find this answer helpful. Thank you.

Two narrow slits are illuminated by a laser with a wavelength of
522 nm. The interference pattern on a screen located x = 4.80 m
away shows that the third-order bright fringe is located y = 9.10
cm away from the central bright fringe. Calculate the distance
between the two slits.
The screen is now moved 0.9 m further away. What is the new
distance between the central and the third-order bright fringe?

Two narrow slits are illuminated by a laser with a wavelength of
578 nm. The interference pattern on a screen located x = 4.50 m
away shows that the third-order bright fringe is located y = 9.10
cm away from the central bright fringe. Calculate the distance
between the two slits.
First you have to calculate the angle of the maximum. Then you
can use the formula for bright fringes of double slits.

Two narrow slits are illuminated by a laser with a wavelength
of 543 nm. The interference pattern on a screen located x = 4.50 m
away shows that the third-order bright fringe is located y = 7.20
cm away from the central bright fringe. Calculate the distance
between the two slits. ("1st order" means m=1, "second order" means
m=2, etc).

illuminated by a laser with a wavelength of 534 nm. The
interference pattern on a screen located x = 5.30 m away shows that
the fourth-order bright fringe is located y = 7.70 cm away from the
central bright fringe. Calculate the distance between the two
slits.
The screen is now moved 2.1 m further away. What is the new
distance between the central and the fourth-order bright
fringe?

In Young's double-slit interference experiment, it is found that
the second bright fringe is at the angle of 10.2.
If the separation between the double slits is
mm, find the wavelength (in m) of the light source. Express your
answer in scientific notation.

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?

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...

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

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
