Question

In Young’s Double Slit Experiment, light of wavelength 550 nm illuminates two slits which are separated by 0.500 mm. The separation between adjacent bright fringes on a screen 3.00 m from the slits is?

1.32mm

0.891 mm

2.54 mm

3.30 mm

I got 3.30mm, wanted to double check

Answer #1

Separation between the adjacent bright Fringes can be calcualate using below formula

Where D= distance of screen from two slits

d= distance between two slits

. Separation between adjacent bright Fringes,

In Young’s Double Slit Experiment, light of wavelength 550 nm
illuminates two slits which are separated by 0.500 mm. The
separation between adjacent bright fringes on a screen 3.00 m from
the slits is?

A double-slit experiment is performed with sodium light
(λ = 589.0 nm). The slits are separated by 1.14 mm, and
the screen is 2.310 m from the slits. Find the separation between
adjacent maxima on the screen.

Light of wavelength 550 nm is used in a double-slit interference
experiment in which the slits are 0.06 mm wide, 0.15 mm apart, and
2.0 m from a screen. At what angle is the third-order diffraction
minimum found?
a) 0.63°
b) 0.74°
c) 1.84°
d) 1.58°

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 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 Young’s double-slit experiment, what happens to the spacing
between the fringes if (a) the slit separation is increased? (b)
the wavelength of the incident light is decreased? (c) if the
distance between the slits and the viewing screen is increased?

In
a double slit experiment light of wavelength 515.0 nm is used, the
separation of the slits is 0.100 mm and the viewing screen is 17.0
cm from the slits. On this screen, what is the separation between
the fifth maximum and seventh minimum from the central
maximum?

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

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 pair of slits, separated by 0.1 mm, is illuminated by light
having a wavelength of 500 nm. An interference pattern is observed
on a screen 1.20 m from the slits. (a) Draw the diagram of the
double slits and determine how far apart will adjacent bright
interference fringes on the screen? (b) What are the angles of the
first and second order fringes with respect to the zeroth order
fringe? (c) Determine the position of the first and second...
