calculate the mass of a photon with wavelength 3.6 A

Answer

`6.135xx10^(-33)kg`

Explanation

For a photon, `lambda=(h)/(m c) or (h)/(lambda c)`
`h=6.626xx10^(-34) "kg" m^(2)s^(-1), lambda=3.6Ã…=3.6xx10^(-10)m, c=3xx10^(8) m s^(-1)`
`:. " " m=((6.626xx10^(-34)"kg"m^(2)s^(-1)))/((3.6xx10^(-10)m)xx(3xx10^(8) ms^(-1)))=6.135xx10^(-33)"kg"`.
