Answer: The energy of one photon of the radiation is [tex]1.52\times 10^{-15}J[/tex]
Explanation:
To calculate the energy of the radiation, we use the equation:
[tex]E=\frac{hc}{\lambda}[/tex]
where,
[tex]\lambda[/tex] = wavelength of the light = [tex]1.3\AA=1.3\times 10^{-10}m[/tex] (Conversion factor: [tex]1m=10^{10}\AA[/tex] )
c = speed of light = [tex]3\times 10^8m/s[/tex]
h = Planck's constant = [tex]6.6\times 10^{-34}Js[/tex]
E = energy of 1 photon
Putting values in above equation, we get:
[tex]E=\frac{6.6\times 10^{-34}Js\times 3\times 10^8m/s}{1.3\times 10^{-10}m}\\\\E=1.52\times 10^{-15}J[/tex]
Hence, the energy of one photon of the radiation is [tex]1.52\times 10^{-15}J[/tex]
