PhysicsEasysingle choice

For pair production i.e. for the production of electron and positron, the incident photon must have a minimum frequency of the order of

Options:

Answer:

Solution:

Minimum energy involved in pair production is 1.02 MeV

$h ν = 1.02 M e V$

$ν = \frac{1.02 \times 10^{6} \times 1.6 \times 10^{- 19}}{6.62 \times 10^{- 34}}$

$ν \approx 10^{40} \times 10^{- 19}$

$ν \approx 10^{21} s^{- 1}$
