Question

Two lasers are shining on a double slit, with slit separation d. Laser 1 has a wavelength of d/20, whereas laser 2 has a wavelength of d/15. The lasers produce separate interference patterns on a screen a distance 4.00 mm away from the slits.

What is the distance Δymax−max between the first maxima (on the same side of the central maximum) of the two patterns?

What is the distance Δymax−min between the second maximum of laser 1 and the third minimum of laser 2, on the same side of the central maximum?

Answer #1

Two lasers are shining on a double slit, with slit separation
d. Laser 1 has a wavelength of d/20, whereas
laser 2 has a wavelength of d/15. The lasers produce
separate interference patterns on a screen a distance 4.00 m away
from the slits.
Part A: What is the distance ?ymax?max between the
first maxima (on the same side of the central maximum) of the two
patterns? Answer must be in meters
Part B: What is the distance ?ymax?min between...

A laser with wavelength
d/8 is shining light on a double slit with slit
separation 0.400mm
. This results in an interference pattern on a screen a distance
L away from the slits. We wish to shine a second
laser, with a different wavelength, through the same slits.
A) What is the wavelength ?2 of the second laser that
would place its second maximum at the same location as the
fourth
minimum of the first laser, if d = 0.400mm...

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...

Find the wavelength of the laser through two slits. The distance
between the slit to the screen is 1 meter, the two slits are
separated by 0.01 mm, and the distance between interference maxima
is 6.33 cm. The angle is also 3.63 degrees between the first maxima
(center) and the second maxima, with an order of m =1. What color
laser is this, and does your answer match up with the wavelength of
a HeNe laser?

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.

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 slits. What is the distance (in meters) from the
central bright fringe to the 3nd dark fringe?

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 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 slits. What is the distance (in cm) between the
2nd and 3rd dark fringes?

In the double-slit experiment, Michelle strongly believes the
slit separation printed by factory is wrong and it should read 2.0
mm. She placed a screen 2.0m from the slits. Vincent illuminates
the slits with two lasers one with wavelengths of700 nm and the
other of 450 nm simultaneously. At what distance from the central
maximum on the screen will a bright fringe from one pattern first
coincide with a bright fringe from the other?

In a double-slit experiment, if the slit separation is
increased, how will the interference pattern on the screen change?
If instead, you increase the distance between the slit and the
screen, how will the interference pattern change? (i.e. the maxima
and minima stay in the same position, get further apart, get closer
together, etc.)
