Question

calculate mass of photon with wavelength 3.6 A . ?

Answer 1

given : wavelength = 3. 6 Ao = 3.6 x 10 -10 m

we need to know that velocity of light = velocity of photon = 3 x 10 8 ms-1



= 6.626 x10-34 kg m2 s -2 / ( 3.6 x 10 -10 m ) ( 3 x 10 8 ms-1 )

= 6.626 x 10 -34 / 10.8 x 10 -2

= 0.613 x 10 -32 = 6.13 x 10 -33 kg

hope u got it !

Answer 2

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

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