A beam of electron is used `YDSE` experiment . The slit width is d when the velocity of electron is increased ,then

(a) No interference is observed

(b) fringe with increases

(d) fringe width remains same

Text Solution

Verified by Experts

The correct Answer is:

Momentum of the electron will increase. So the wavelength `(lambda=h//p)` of electron will decrease and fringe width decreases as `betaproplambda`
