A particle having rest mass m(0) travel ...

A particle having rest mass `m_(0)` travel with speed of light in vaccum.Its de-Broglie wavelength will be…..

A

`(h)/(m_(0)c)`

B

0

C

`oo`

D

`(m_(0)C)/(h)`

Text Solution

Verified by Experts

The correct Answer is:
B

`lambda=(h)/(mv)`
`lambda=(hxxsqrt(1-(v^(2))/(v^(2))))/(m_(0)v) therefore m=(m_(0))/(sqrt(1-v^(2)/(c^(2))))`
`lambda=(hxxsqrt(1-c^(2)/(c^(2))))/(m_(0)v) therefore v=c`
`therefore lambda=0`
