Answer: The energy of one photon of the given light is [tex]3.79\times 10^{-19}J[/tex]
Explanation:
To calculate the energy of one photon, we use Planck's equation, which is:
[tex]E=\frac{hc}{\lambda}[/tex]
where,
[tex]\lambda[/tex] = wavelength of light = [tex]525nm=5.25\times 10^{-7}m[/tex] (Conversion factor: [tex]1m=10^9nm[/tex] )
h = Planck's constant = [tex]6.625\times 10^{-34}J.s[/tex]
c = speed of light = [tex]3\times 10^8m/s[/tex]
Putting values in above equation, we get:
[tex]E=\frac{6.625\times 10^{-34}J.s\times 3\times 10^8m/s}{5.25\times 10^{-7}mm}\\\\E=3.79\times 10^{-19}J[/tex]
Hence, the energy of one photon of the given light is [tex]3.79\times 10^{-19}J[/tex]
