Answer 2

Answer:

The mass of photon having wavelength 1nm is $2.20\times 10^{-33} kg$.

Explanation:

De-Broglie wavelength is calculated by using the formula:

$\lambda=\frac{h}{mv}$

where,

$\lambda$ = wavelength of particle

h = Planck's constant = $6.625\times 10^{-34}Js$

m = mass of particle=

v = velocity of particle

$m=\frac{6.625\times 10^{-34}Js}{1 \times 10^{-9}m\times 3\times 10^8 m/s}$

$m=2.20\times 10^{-33} kg$

The mass of photon having wavelength 1nm is $2.20\times 10^{-33} kg$.
