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

Monochromatic light of wavelength λ = 595 nm from a distant
source passes through a slit 0.460 mm wide. The diffraction pattern
is observed on a screen 4.00 m from the slit. In terms of the
intensity I0 at the peak of the central maximum, what is the
intensity of the light at the screen the following distances from
the center of the central maximum?

b) 3.00mm
c) 5.00 mm

Light with a wavelength of 550 nm is incident on a single slit,
creating a diffraction pattern on a distant screen 2.5 m away. At a
point on the diffraction pattern that is 1.443 m from the central
maximum, the path length difference between the ray from the top of
the slit and the bottom of the slit results in a phase difference
of 6π radians. What is the width of the slit? (a) 1.1 µm (b) 2.2 µm
(c)...

Light from a source of wavelength 475 nm passes through a single
slit and falls on a screen 2.5 m away. If the slit width is 2.00 x
10^-6 m, how many maxima occur, including the central maximum?
A student performs Young's double-slit experiment using a slit
separation of 21.6 mm. A screen is placed 3.00 m from the centre of
the sources such that a point on the fifth nodal line is 37.5 cm
from the centre of the...

Monochromatic light of wavelength 466 nm from a distant source
passes through a slit that is 0.0330 mm wide. In the resulting
diffraction pattern, the intensity at the center of the central
maximum (? = 0?) is 1.06×10?4 W/m2 . What is
the intensity at a point on the screen that corresponds to
? = 1.20?.

Light of wavelength 492.0 nm passes through a 0.10-mm wide slit
and forms a diffraction pattern on a screen 2.6 m away from the
slit. Calculate the distance between the first and the third minima
on the same side of the central maximum.

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?

Light of a wavelength of 550nm passes through a 10 µm wide slits
on to a screen 1m away from the slit.
A) How far either side of the central maximum at the 1st, 2nd
and 3rd dark regions in the diffraction pattern?
B) What is the maximum possible number of bright fringes that
could be viewed either side of the central maximum in perfect
conditions?

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.
