∴

E = 6.6E-34 \cdot \frac{3E+8m/s}{1E-7m}

Next Step Prepare to Evaluate

∴

E = 6.6E-34 \cdot \frac{3E+8}{1E-7}

Next Step Evaluate

∴

E = 1.98644582417176E-18J

LAST Step Rounding Answer

∴

E = 2E-18J

How to Evaluate Energy of photon?

Energy of photon evaluator uses Energy of photon = [hP]*[c]/Wavelength of photon to evaluate the Energy of photon, Energy of photon (light) is directly related to the photon's electromagnetic frequency. The energy of photon depends on wavelength in such a way that the energy of photon is inversely proportional to the wavelength. The higher is the photon energy frequency, the higher its energy. Energy of photon is denoted by E symbol.
