Hope this will help bro...Follo me

Answer 2

Answer:

1.33 * 10^-27 kg m/s

Explanation:

Given,

Wavelength of photon = λ = 500 nm

Momentum of a photon of light can be given as:

p = h/λ where, h = 6.63 × 10^-34 J-s

p = 6.63 × 10^-34 / 500

p = 1.326 * 10^-27 kg m/s

or, p = 1.33 * 10^-27 kg m/s

Therefore the momentum of a photon of light of wavelength 500nm is 1.33 * 10^-27 kg m/s.
