Question

A flat screen is located 0.43 m away from a single slit. Light with a wavelength of 610 nm (in vacuum) shines through the slit and produces a diffraction pattern. The width of the central bright fringe on the screen is 0.057 m. What is the width of the slit?

Answer #1

Light shines through a single slit whose width is 5.6 × 10-4 m.
A diffraction pattern is formed on a flat screen located 4.0 m
away. The distance between the middle of the central bright fringe
and the first dark fringe is 3.3 mm. What is the wavelength of the
light?

1. monochromatic light of wavelength 540 nm from a source passes
through a slit that is 0.03mm wide. What is the width of the
central bright fringe on the diffraction pattern formed on a screen
placed at a distance of 2.00 m away from the slit?
2. Light of wavelength 500 nm is incident on a single slit of
width 0.02 mm to produce a diffraction pattern with intensity
4.00×10^-4 W/m^2 at the center of a screen placed far away...

Red light of wavelength 633 nm from a helium-neon laser passes
through a slit 0.350 mm wide. The diffraction pattern is observed
on a screen 2.55 m away. Define the width of a bright fringe as the
distance between the minima on either side.
a) What is the width of the central bright fringe?
b) What is the width of the first bright fringe on either side
of the central one?

Red light of wavelength 633 nm from a helium-neon laser passes
through a slit 0.400 mm wide. The diffraction pattern is observed
on a screen 3.25 m away. Define the width of a bright fringe as the
distance between the minima on either side.
Part A: What is the width of the central bright fringe?
Part B: What is the width of the first bright fringe on either
side of the central one?

Light of wavelength 550 nm is incident on a single slit. On a
screen 170 cm away, the central bright spot is 0.60 mm wide. What
is the width of the slit?

Light of wavelength 610 nm falls on a slit that is 3.80×10?3 mm
wide. How far the first bright diffraction fringe is from the
strong central maximum if the screen is 12.5 m away.

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 diffraction pattern incident on a screen that is 5.1 m away is
produced using light that passes through a single-slit of width 590
um. The central maximum is 1.4 cm wide. If the single-slit is
replaced with a double-slit with a slit separation of 0.40 mm and
the same light is used, what would be the distance from the central
maximum to a fifth dark fringe?

Light of wavelength 755.0 nm passes through a single slit of
width 2.20 µm, and a diffraction pattern is observed on a screen
24.5 cm away. Determine the relative intensity of light
I/Imax at 14.0 cm away from the
central maximum.

Light with a wavelength of 460 nm is incident on a single slit
with a slit width of 1.55 mm. A Single Slit Diffraction
Pattern is observed on a screen that is 1.55 m away from
the slit.
