Question

Calculate mass of a photon with wavelength of 3.6 angstrom

Answer 1

Explanation:

I I have solved the above question in the given text.

Answer 2

Explanation:

We know that,

$\underline{\boxed{\sf m=\dfrac{h}{λ \nu}}}$

We have,

• $\sf λ=3.6 × 10^{-10} \: m$
• $\sf h = 6.626×10^{-34} \: Js$
• $\sf \nu = c = 3×10^{8} \: m/s$

$\sf m = \dfrac{6.626×10^{-34}\: Js }{(3.6×10^{10} \: m)(3×10^8 \: m/s)}$

$\sf m = \bf 6.135×10^{-29} \: kg$
