Question

calculate the mass of photon with λ 6.3 a

Answer 1

lemda=h/mc
=>m=h/3*10^8*6.3*10^-10
=>m=6.62*10^-34/3*10^8*6.3*10^-10
=>m=33*10^-34
Calculate exact value ans is approx

Answer 2

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

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