Assertion : The energy (E ) and momentum...

Assertion : The energy `(E )` and momentum `(p)` of a photon are related by `p = E//c`.
Reason : The photon behaves like a particle.

A

If both assertion and reason are ture and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason both are false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

Momentum of a photon is given by `p = (h)/(lambda)` Also the photon is a from of energy packets behaves as a particle having energy
`E = (hc)/(lambda). So p = ( E)/( C)`
