In a Young's double-slit experiment the wavelength of light used
is 493 nm (in vacuum), and the separation between the slits is 1.5
× 10-6 m. Determine the angle that locates
(a) the dark fringe for which m = 0,
(b) the bright fringe for which m = 1,
(c) the dark fringe for which m = 1, and
(d) the bright fringe for which m =
2.

In a Young's double-slit experiment the wavelength of light used
is 489 nm (in vacuum), and the separation between the slits is 2.4
× 10-6 m. Determine the angle that locates (a) the dark fringe for
which m = 0, (b) the bright fringe for which m = 1, (c) the dark
fringe for which m = 1, and (d) the bright fringe for which m =
2.

In a Young's double-slit experiment the wavelength of light used
is 457 nm (in vacuum), and the separation between the slits is 1.7
× 10-6 m. Determine the angle that locates (a) the dark fringe for
which m = 0, (b) the bright fringe for which m = 1, (c) the dark
fringe for which m = 1, and (d) the bright fringe for which m =
2.

In Young's double-slit interference experiment, it is found that
the second bright fringe is at the angle of 10.2.
If the separation between the double slits is
mm, find the wavelength (in m) of the light source. Express your
answer in scientific notation.

In a Young's double-slit experiment, light of wavelength
? is sent through the slits. The intensity I at
angle ?0 from the central bright fringe is
lower than the maximum intensity Imax on the
screen. Find an expression for the spacing between the slits in
terms of ?, ?0, I, and
Imax.

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...

In a double-slit interference experiment, the slit separation is
2.29 μm, the light wavelength is 532 nm, and the separation between
the slits and the screen is 4.42 m. (a) What is
the angle between the center and the third side bright fringe? If
we decrease the light frequency to 94.8% of its initial value,
(b) does the third side bright fringe move along
the screen toward or away from the pattern's center and
(c) how far does it move?

In a Young's double-slit experiment, a set of parallel slits
with a separation of 0.104 mm is illuminated by
light having a wavelength of 566 nm and the

In a Young's double-slit experiment, a set of parallel slits
with a separation of 0.150 mm is illuminated by light having a
wavelength of 600 nm and the interference pattern observed on a
screen 4.50 m from the slits.
(a) What is the difference in path lengths from the two slits to
the location of a fifth order bright fringe on the screen? μm
