When the velocity of an electron increases, its de Broglie wavelength

A

increases

B

decrease

C

remains same

D

may increase or decrease

Text Solution

Verified by Experts

The correct Answer is:
B
The de Broglie wavelength is given be
`lamda =(h)/(p) = h/(mv)`
So if the velocity of the electron increases , the de Broglie wavelength decrease.
