What should be the mass of the sodium photon if its wavelength is `5894Å`, the velocity of light is `3xx10^(8)` metre//second and the value of `h` is `6.6252xx10^(-34)kg m^(2)//sec`. ?

Options

A. `3.746xx10^(-26)`
B. `3.746xx10^(-30)`
C. `3.746xx10^(-34)`
D. `3.746xx10^(-36)`

Explanation

`lambda=(h)/(mxxc) implies m=(h)/(clambda)`
`(because lambda=5894Å=5894xx10^(-10)m)`
`m=(6.6252xx10^(-34))/(3xx10^(-8)xx5894xx10^(-10)) " "or" "(6.652)/(17682)xx10^(-32)`
`=0.0003746xx10^(-32)=3.746xx10^(-36)kg`
