The term coherence relates to ______.
the phase relationship between two waves
the polarization state of two waves
the diffraction of two waves
the amplitude of two waves
What does one observe on the screen in a Young's experiment if white light illuminates the double slit instead of light of a single wavelength?
A white central fringe and no other fringes
A dark central fringe and a series of alternating white and dark fringes on each side of the center
A white central fringe and a series of colored and dark fringes on each side of the center
A continuous band of colors with no dark fringes anywhere
In a Young's double slit experiment, green light is
incident on the two slits. The interference pattern is
observed on a screen. Which one of the following
changes would cause the fringes to be more closely
spaced?
Reduce the slit separation distance
Use red light instead of green light
Use blue light instead of green light
Move the screen farther away from the slits
In a double-slit interference experiment you are
asked to use laser light of different wavelengths and
determine the separation between adjacent maxima.
You observe that this separation is greatest when you
illuminate the double slit with _____.
blue light
green light
yellow light
red light
Two light sources are said to be coherent if they are ______.
of the same frequency
of the same frequency, and maintain a constant phase difference
of the same amplitude, and maintain a constant phase difference
of the same frequency and amplitude
Two beams of coherent light start out at the same
point in phase and travel different paths to arrive at
point 𝑃. If the maximum constructive interference is
to occur at point 𝑃, the two beams must travel paths
that differ by _______.
a whole number of wavelengths
a whole number of half-wavelengths
an odd number of wavelengths
an odd number of half-wavelengths
Two beams of coherent light start out at the same

It is shone through a double slit spacing 0.2mm onto a screen 2m away.
The fringe spacing is?
In Young's Double slit experiment, two adjacent bright fringes are 0.5 cm apart. The distance between two dark fringes ______.
is less than 0.5 cm
is greater than 0.5 cm
is exactly 0.5 cm
is dependent on which order is observed.
In a Young's double-slit experiment, the slit separation is doubled. To maintain the same fringe spacing on the screen, the screen-to-slit distance D must be changed to:
D/2
D 2
2D
4D
