Question

A material particle with a rest mass m₀ is moving with speed
of light c. The de-Broglie wavelength associated is given
by
(a) h/m₀c
(b) m₀c/h (c) zero (d) [infinity]

Answer 1

Answer:

Dea Student,

Speed of the electron, v=0.5c (c is speed of light which is 3×108 ms−1)v=0.5× 3×108 ms−1 =1.5×108 ms−1

According to De Broglie's equation

λ (wavelength)=h (Planck's constant)p (momentum)=hmv

λ=hmv=6.626×10−34J s9.11×10−31Kg ×1.5×108ms−1=4.848×10−12 m
