Question

If a particle of lgm mass moves with velocity of light than calculate wave length.​

Answer 1

Answer:

The wavelength of de Broglie wave is given by, λ=

p

h

​

 where h= Planck's constant and p= momentum of the particle.

Now, p=mv, here m=

1−v

2

/c

​

m

0

​

​

, relativistic mass of the particle.

Given, v=c so m=∞

Thus, p=∞

Hence, λ=

∞

h
