No fringes are seen in a single-slit diffraction pattern if
.....
the distance to the screen is greater than the slit width
the wavelength is less than the distance to the screen
the wavelength is greater than the slit width
the screen is far away
the wavelength is less than the slit width
A single-slit diffraction pattern is formed on a distant screen.
If the width of the single slit through which light passes is
reduced, what happens to the width of the central bright fringe?
Assume the angles involved remain small.
The
central bright fringe becomes
wider.
The
central bright fringe remains the same
size.
The
effect cannot be determined unless the distance between the slit
and the screen is
known.
The
central bright fringe becomes narrower.
In a single slit experiment, the central maximum is:
The same size as all of the other maximums.
Twice the size of the other maximums.
Half the size of the other maximums.
Just slightly larger than the other maximums.
Electrons would be ejected from silver if the incident light had
a frequency of:
1.03 x 1015 Hz
1.02 x 1015 Hz
1.01 x 1015 Hz
None of the options is correct
What is the mass equivalent of an x-ray with...
I see demonstrations of single slit diffraction associated with
the uncertainty principle. Is single slit diffraction a result of
uncertainty, or is this just a demonstration to help understand
uncertainty?
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?
How does the single-slit diffraction pattern look in comparison
to the double-slit interference pattern? Is it possible to have a
double-slit pattern without the single-slit pattern overlaid?
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
Why does multiple slit experiment have unequal fringes?
What is the effect of adding more slits?
What is the effect of increasing the width of the slit in a
double slit experiment?
In a double slit interference measurement, 6 full bright fringes
are inside the second secondary diffraction peak. The bright
fringes are completely covered by diffraction minima. The slit
separation is 20 micrometers. The distance between the slits and
the screen is 1.3m. Laser of wavelength 532 nm is
used.
a) How many full interference bright fringes can you see within
the central diffraction peak?
b) What interference maximum coincides with the 4th diffraction
minimum?
c) Find the distance on the...
Width of Peak (cm): 1.6 Width of Slit for Single Peak: 2.3
The width of the center peak (w) can be calculated using the
equation w = 2λL/ a
where a is the width of the slit. Use this equation to determine
the width of the slit that caused the diffraction pattern. Show
your work.
I am confused as to what I am finding since I do not have L. I
have going backwards λL = 1.84. If someone could...
