Question

A double-slit set up produces bright fringes for sodium light ( = 589 nm) such that the first bright fringe is at an angle of 0.20°.

(a) What is the slit separation?

(b) Suppose the two slits, the screen, and intervening space are immersed in water, but the source of the sodium light stays outside the water. What will be the wavelength of the sodium light once it enters the water?

(c) What is the location of the first bright fringe (in degrees) for the situation described in part (b)?

Answer #1

A double-slit experiment uses coherent
light of wavelength 633 nm with a slit separation of 0.100 mm and a
screen placed 2.0 m away.
(a) How wide on the screen is the central bright fringe?
(b) What is the distance on the screen between first-order and
second-order bright fringes?
(c) What is the angular separation (in radians) between the
central maximum and the first-order maximum?

Blue light falling on a double-slit produces interference
fringes on a screen. What will happen to the fringes (closer
together, farther apart, remain the same, or no more fringes) if
The blue light is replaced by red light? The blue light is replaced
by incoherent light? The separation between the slits is decreased?
The distance to the screen is decreased? The entire experiment is
immersed in water?

the slits is?

Bichromatic light of wavelengths λ1=572λ1=572 nm and
λ2=647λ2=647 nm is incident on a double-slit plate. The separation
between the slits dd and the width of each slit are not given. The
distance between the viewing screen and the plate is

When light diffracts through a double slit, what causes there to
be bright and dark fringes on a viewing screen beyond the
slits?

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?
