Calculate the energies of the photons as...

Calculate the energies of the photons associated with the following radiation`:`
X-rays of 0.1 nm

Text Solution

Verified by Experts

Wavelength of X-rays `lambda_(x) = 0.1nm`
`= 0.1 xx 10^(-9) m`
`E _(x ) = ( hc)/( lambda_(x )) =( 19.878 xx 10^(-26))/(10^(-10))`
`= 19.878 xx 10^(-16) J`
`= ( 19.878 xx 10^(-16))/( 1.6 xx 10^(-19)) eV = 12. 424 xx 10^(3)`
`E_(x ) = 12424 eV`
