In Young's double-slit experiment, what happens to the spacing
between the fringes if
(a) the slit separation is increased?
(b) the wavelength of the incident light is decreased?
(c) if the distance between the slits and the viewing screen is
increased?
In a Young's double-slit experiment, two parallel slits with a
slit separation of 0.135 mm are illuminated by light of wavelength
579 nm, and the interference pattern is observed on a screen
located 4.15 m from the slits.
(a) What is the difference in path lengths from each of the
slits to the location of the center of a fifth-order bright fringe
on the screen?

In a young's double slit experiment
a) There is no diffraction
b) Diffraction is so small it is not easily seen
c) Diffraction is readily apparent in the interference
pattern
d) Diffraction disappears when the slit separation is integer
times the slit width
(1)(A) Young's double slit experiment is one of the
quintessential experiments in physics. The availability of low cost
lasers in recent years allows us to perform the double slit
experiment rather easily in class. Your professor shines a green
laser (566 nm) on a double slit with a separation of 0.106 mm. The
diffraction pattern shines on the classroom wall 4.0 m away.
Calculate the fringe separation between the fourth order and
central fringe.
(B)Working in lab class you shine...
In a Young's double-slit experiment the wavelength of light used
is 462 nm (in vacuum), and the separation between the slits is 2.1
× 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 =

In a Young's double-slit experiment, a set of parallel slits
with a separation of 0.102 mm is illuminated by light having a

lengths from the two slits to the location of a second order bright
fringe on the screen?
