Question

The momentum of photon with energy 20 EV is plz give ans with explanation ​

Answer 1

Answer:

Explanation:E = pc where p is relativistic momentum of photon and c is speed of light

E = 20 eV = 20 x 1.6 x 10^-19 J

p = ?

c ~ 3 x 10^8 m/s

p = 20 . 1.6 . 10^-19 / 3 . 10^8

p ~ 10.6 x 10^-27 kg. m/s

Answer 2
