Worksheet time: 6mins
In Young’s Double Slit Experiment, if instead of light white light is used, what would be the observation?
The pattern will not be visible
The shape of the pattern will change from hyperbolic to circular
Colored fringes will be observed with a white bright fringe at the center
The bright and dark fringes will change position
What kind of sources are required for Young’s Double Slit experiment?
Coherent
Incoherent
Intense
Bright
If the distance between the two slits is doubled, the fringe width _________
Doubles
Halves
Four-times
Remains same
What change is observed when the whole pattern is immersed in water?
Fringe width decreases
Fringe width increases
Colored fringes
The bright and dark fringes will change position
The following intensity variation is observed in a Young’s Double Slit Experiment.
True
False
There is no effect on the interference pattern when the width of the slit is increased.
True
False
The fringe width in a Young 's double slit experiment can be increased if we decrease
separation of slits
width of slits
wavelength of light used
distance between slits and screen
If Young's double slit experiment is performed in water keeping the rest of the set-up same, the fringe will
decrease in width
not be formed
increase in width
remain unchanged
In Young's double slit experiment, one slit is covered with red filter and another slit is covered by green filter, then interference
invisible
green
red
yellow
When a light wave enters into a medium of different optical density,
its speed and frequency change
its speed and wavelength change
its frequency and wavelength change
its speed, frequency, and wavelength change
Two light sources are said to be coherent if they
are of the same frequency
are of the same frequency, and maintain a constant phase difference
are of the same amplitude, and maintain a constant phase difference
are of the same frequency and amplitude
