Question

Calculate the mass of photon with wavelength 3.6a°

Answer 1

lamda = 3.6 angstrom = 3.6 x 10^-10 

Answer 2

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

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