Question

Calculate the mass of a photon with wavelength 3.6a°

Answer 1

hey

as you know

wavelength=h/mv

Answer 2

${\huge{\underline{\underline{\mathcal{\green{♡ANSWER♡}}}}}}$

• ⭐. λ =${3.6Å=3.6×10^-10m}$
• ⭐$\red{\tt{Velocity of photon}}$=$\purple{\tt{Velocity of light}}$
• ⭐${m}$=$\frac{h}{λv}$
• ⭐= $\frac{6.626×10^-34Js}{(3.6×10^-10m)(3×10^8 ms^-1)}$
• ⭐${6.135×10^-33kg}$
