Answer 2

Solution If the light is behave as a particle, there two of bright spots appear in the double slit experiment. Explanation If light considered as particle, and these particle through the double slit experiment is allowed to strike on the screen on the other side we would able to see a pattem corresponding to the size and shape of the slit. In a double slit experiment the pattern on the screen is diffraction pattern in which couple of rays of light hit exactly on the slits If the light is behave as a wave, there many number of bright spots appear in the doubleslit experiment Explanation If light considered as wave, and these wave through the double slit experiment is allowed to strike on the screen on the other side we would able to see a pattem corresponding to the size and shape of the slit. In a double slit experiment the pattem on the screen is diffraction pattern in which more light spot is spread out in all direction C) Destructive interference causes, when the crest of one wave lines up with the trough of another wave
