Integrated ConceptsA 1.00-fm photon has a wavelength short enough to detect some information about nuclei. (a) What is the photon momentum? (b) What is its energy in joules and MeV? (c) What is the (relativistic) velocity of an electron with the same momentum? (d) Calculate the electron's kinetic energy.

To determine

(a)

A1fm photon has a wavelength short enough to detect some information about nuclei. Find the momentum of photon

Explanation

Given Data:

Given that a1fm photon has a wavelength short enough to detect some information about nuclei

Formula Used:

De-Broglie equation is given as

λ=hP

Whereh= Planck's constant

P= Momentum

Calculation:

We haveλ=1fm=1×1015m

h=6.63×1034kg.m/s

Momentum is calculated as follows:

P=hλ

Substituting the values in the above equation, we get

P=6

To determine

(b)

A1fm photon has a wavelength short enough to detect some information about nuclei. The photon momentum is6.63×1019kg.m/s . Find its energy in joules and MeV.

To determine

(c)

The velocity of an electron with the same momentum.

To determine

(d)

The kinetic energy of electron.
