Final answer:
In YDSE, when one of the two slits is covered by a transparent paper that transmits only half the light intensity, the intensity of the maxima will remain unchanged, while the intensity of the minima will decrease by half.
Step-by-step explanation:
In YDSE, when one of the two slits is covered by a transparent paper that transmits only half the light intensity, the intensity of the maxima will remain the same, while the intensity of the minima will decrease by half.
This can be explained by considering that in Young's double-slit experiment, the bright fringes or the maxima are formed due to constructive interference, where the waves from the two slits reinforce each other. Therefore, covering one slit with the transparent paper will not affect the constructive interference and the intensity of the maxima will remain unchanged.
However, the dark fringes or the minima are formed due to destructive interference, where the waves from the two slits cancel each other out. When one slit is covered and transmits only half the light intensity, it weakens the wave from that slit and reduces the destructive interference, resulting in a decrease in the intensity of the minima by half.
