Answer:
Energy of a photon is [tex]3.313\times 10^{-19}\textrm{ J}[/tex]
Explanation:
Given:
Frequency of the photon is, [tex]f=5.0\times 10^{14}\textrm{ Hz}[/tex].
Energy of a photon of frequency [tex]f[/tex] is given as:
[tex]E=hf[/tex], where, [tex]h[/tex] is called Planck's constant.
[tex]h = 6.626\times 10^{-34}\textrm{ J.s}[/tex]
So, energy of a photon is:
[tex]E= 6.626\times 10^{-34}\times 5.0\times 10^{14}=3.313\times 10^{-19}\textrm{ J}[/tex]
Therefore, the energy of a photon whose frequency is [tex]5.0\times 10^{14}[/tex] Hz is [tex]3.313\times 10^{-19}\textrm{ J}[/tex].
