Question

Calculate the mass of a photon with wavelength 3.6

Answer 1

Lambda=3.6Å=3.6*10-10m

Velocity of photon =velocity of light

M=h/lambda*v =6.626*10-34js/(3.6*10-10m)(3*10 8 m/s)

=6.135*10 -29 Kg

Answer 2

Answer:it is solved below

Explanation:

Given, wavelength ( lambda)=3.6

To find: mass of photon (m)=?

We know, by De Broglie's equation,

Mass(m)= h(Planks const)/lambda × velocity of light in vacuum

Therefore, m=6.626×10^-34/(3.6)(3×10^8)

Calculate and get the answer
