Question

In a double-slit experiment, light with a wavelength λ passes through a double-slit and forms an interference pattern on the screen at a distance L from the slits. What statement is true for the resulting interference pattern if the frequency of the light increases?

The distance between maxima increases.

Not enough information given.

The distance between maxima stays the same.

The distance between maxima decreases.

Answer #1

The distance between maxima will decrease.

Reason: When frequency of incident light is increased, wavelength decreases which results in decrease in fringe width of the pattern; fringe width is the distance between two consecutive bright fringes or two consecutive dark fringes.

So, when fringe width decreases, the maxima of the pattern comes closer or we can say that distance between maxima decreases.

=>fringe width=(wavelength *distance between slit and screen) / distance between slits

A double- slit experiment is performed with a coherent (single
frequency/wavelength) beam of laser light.
1, suppose that the two slits are separated by a distance D= 0.1
mm; the distance (H) between the center of the pattern and the
second ( m=2) bright region is 1.0 cm; and the distance(L) between
the screen and the slits is 1.0 m. use the results of this
experiment to determine the wavelength of the light.
2. Suppose that the frequency of the...

Blue light (λ = 450 nm) is used in a double slit experiment. The
light passes through
a diffraction grating with 1250 lines per centimeter, and the light
is projected onto a
screen, which is 1.75 m from the slits. What is the distance from
the central bright spot
to the third order maximum? What is the distance from the central
bright spot to the
second order minimum?

1. A double slit apparatus is held 1.2 m from a screen. Red
light (λ = 600.0nm) is sent through the double slit and the
interference pattern on the screen shows a distance of 12.5cm
between the central fringe and tenth order bright fringe. What is
the separation of the slits?

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 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 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...

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?

In a double-slit experiment, if the wavelength of the light is
increased, the interference pattern
a)spreads out
b)stays the same
c)shrink together
d)disappears
What happens if slits are moved apart keeping wavelength same.
Explain

Monochromatic light of wavelength λ1 is sent
through two closely-spaced slits separated by a distance
d1 = 1.8 mm. A resulting interference pattern
is shown on a screen L1 away. Another
monochromatic light source, this one of wavelength
λ2, is sent through a diffraction grating
toward the same screen, resulting in a second interference pattern.
The diffraction grating is a distance L2 from
the screen and has 400 lines per mm etched onto it.
A) Assume that L1 = L2...

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.
