What happens when you cover a slit?
When one of the slits is covered, the fringes disappear and there is uniform illumination on the screen. This shows clearly that the bands are due to interference. In such condition, the double slit experiment becomes single slit experiment.
What happens if one slit is covered in YDSE?
In Young’s double slit experiment, if one of the slit is closed fully, then in the interference pattern. If one of slit is closed then interference fringes are not formed on the screen but a fringe pattern is observed due to diffraction from slit.
What happens to the light intensity at the location of a dark fringe when one of the slits is covered up?
When the intensity of ONE of the fringes is reduced, the amplitude of ONE of the fringes is also reduced (I = A²) .
How will the interference pattern of Young’s double slit change if one of the two slits is covered by a paper which transmits only half of the light intensity?
In YDSE, one of two slits is covered by a transparent paper which transmits only half the ligth intensity. As is known, if a and b are amplitude of two waves, then Imax=(a+b)2, and Imin=(a-b)2 When second slit is covered by a transparent paper b decreases. ∴Imax would decrease, and. Imni would increase.
How will intensity of maxima and minima in YDSE change if one of the two slits is covered by a transparent paper which transmits only half of the light intensity?
In young’s double slit experiment, if one of the slits is covered by a transparent paper such that, only half of light intensity is transmitted then, the intensity of maxima decreases and the intensity of minima increases.
How does the intensity of the maxima vary with order no?
The intensity of light of a secondary maximum goes on decreasing with the order of the maximum.
Why the intensity on the screen decreases as we move away from the central Maxima?
I think what you want to know is why the maximum bright spot is the central belt and from it begins to decrease in intensity? the answer is: because the path difference between the center point and the crack and the other parts of the screen have a greater distance.
What happens to the bright fringes Maxima as the number of slits in a diffraction grating is increased?
As N grows larger and the number of bright and dark fringes increase, the widths of the maxima become narrower due to the closely located neighboring dark fringes. As the number of slits increases, more secondary maxima appear, but the principal maxima become brighter and narrower.
