Question

The de-Brogile wavelength of electron is 108, then its velocity in m/sec will be
(A) 7.2 x 10
(B) 72x104 (C) 7.2x10-5 (D) 7.2x10

Answer 1

Answer:

lamda = hmv

lamda = vf

lamda is the de brogile wavelength

v is velocity and f is frequency can also be expressed in time period

108 = v ( 1 )

v = 108

pls pls pls mark as brainliest answer
