Answer: The energy of the photon is [tex]3.95\times 10^{-19}J[/tex]
Explanation:
The relation between energy and wavelength of light is given by Planck's equation, which is:
[tex]E=\frac{hc}{\lambda}[/tex]
where,
E = energy of the photon
h = Planck's constant = [tex]6.626\times 10^{-34}Js[/tex]
c = speed of light = [tex]3.0\times 10^8m/s[/tex]
[tex]\lambda[/tex] = wavelength of photon = 503 nm = [tex]503\times 10^{-9}m[/tex] (Conversion factor: [tex]1m=10^9nm[/tex] )
Putting values in above equation, we get:
[tex]E=\frac{6.626\times 10^{-34}Js\times 3.0\times 10^8m/s}{503\times 10^{-9}m}\\\\E=3.95\times 10^{-19}J[/tex]
Hence, the energy of the photon is [tex]3.95\times 10^{-19}J[/tex]
