The energy of photon is equal to 3 kilo eV. Cal. its linear momentum.​

Answer 1

Explanation:

The energy of photon is equal to 3 kilo ev. Calculate it's linear momentum? The energy of photon is equal to 3 kilo ev. Calculate it's linear

Answer 2

Answer:

☑️☑️☑️☑️☑️☑️☑️

Here....

E = 3 kilo eV. = 3000 x 1.6 x 10^-19

E = hc/lemda(Wave lenght)........(1)

AccorDinG To De Broglie's equation....

Lemda = h/mv.......v=c speed of light (photon)...

Lemda(wave lenght) = h/mc

h/lemda = mu = momentum = p

So.....From equation (1).....

P(Momentum) = E/c

i.e. P = 3000 x 1.6 x 10^-19 / 3 x 10^8

P = 1.6e - 8..... Or...

P (Linear Momentum)= 1.6 x 10 ^-24
