If wavelength of photon is `2.2 xx 10^(-11)m`, `h = 6.6 xx 10^(-34) Js`, then momentum of photons is

Options

A. `3 xx 10^(-23) kg//s`
B. `1.452 xx 10^(-44) kg//s`
C. `3.33 xx 10^(22) kg//s`
D. `6.89 xx 10^(43) kg//s`

Answer

A

Explanation

`p = (h)/(lambda) = (6.6 xx 10^(-34))/(2.2 xx 10^(-11)) = 3 xx 10^(-23) kg m s^(-1)`
