Find the wavelength (in nm) of a photon whose energy is 9.00 × 10-19 J.

Find the wavelength (in nm) of a photon whose energy is 9.00 × 10^-19 J.

Expert Solution

Given data

Energy(E)=9.00*10^(-19)

We know(E)=hf ( f=c/lamda)

So E=hc/lamda

Lamda =hc/E

=(6.63)*^10(-34)*(3)*10(^8)/(9.00)*10^(-19)

=(6.63)*(3)*(10)^(-26)(/9.00)*(10)^(-19)

=(19.89/9.00)*10(-7)

=2.21*10(-7) meters

=221 nm
