what double slit experiment please explain in briefly?
Answers
The double-slit experiment in quantum mechanics is an experiment, which was first performed by physicist Thomas Young in 1801. It shows that light has both a wave nature or characteristic and a particle nature or characteristic, and that these natures are inseparable. So, light is said to have wave–particle duality rather than be only a wave or only a particle. The same is true for electrons and other quantum particles....
The base version of this experiment is very simple. It requires only a double slit device like the one in the picture, something to hold the double slit device still, and a good laser such as the kind that is used by workmen to "draw" straight lines when they are building. The laser is supported so it can only be moved on purpose. It is aimed at the central point between the two slits from a point about one half meter away. Something like a movie screen or a smooth white wall is put up on the other side of the double slit device several meters away. When everything is fixed, a pattern of light and dark bands will show up....
thnx.....
mark as brilliant and follow me.....
Answer:
In modern physics, the double-slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles; moreover, it displays the fundamentally probabilistic nature of quantum mechanical phenomena.
