U need to have a laser light and a card board with two pin holes very close to each other . And screen should be far away from the pin holes. Whole apparatus must be kept in dark..

Ok,bt when pn junction diode is formed then barrier potential is setup which can be determined practically, is thr any way to find barrier potential theoritically?

Any 1here to help me out of this.

The answer may lie in energy band of the solid. As we know that due to interaction between the atoms they forms continues band. They are discrete but the spacing is extremely small so the radiation emitted also will too have continues emission.

I want to know that when a pn junction diode is formed and barrier potential is setup then how can we determine the same theoretically. Also I wan to know that is there any relation between barrier potential and energy band gapSmall band gap small barrier? ?

U mean that silicon atom is now free to move in the lattice? ?

Any one here to reply

When we doped phosphorus in site of silicon then some silicon is replaced and phosphorus is added to the site . Now I am asking for that silicon atom ??

I want to know ... what happens to silicon when some impurity is added to it. Where does silicon goes??

Ok. I will read . Thank you

Oh no. The justification given in link is not complete. Read it again

Why energy level is higher on p side of pn junction diode as compare to n side of same

Attraction towards the magnet

I agree with your answer. But is that friction enough to avoid attraction on inclined plane

When an iron ball is allow to roll down the inclined plane such that magnet is fixed at the bottom of plane then rolling ball is attracted towards the magnet. But if two iron balls all allow to roll down then they stop in between on plane. Why
