Energy E = hc / l
where h = Planck's constant, c = speed of light and l = wavelength.
E = 1.986 * 10^-25 / 3.8 * 10^-7 = 5.223*10^-19
where h = Planck's constant, c = speed of light and l = wavelength.
E = 1.986 * 10^-25 / 3.8 * 10^-7 = 5.223*10^-19
Wavelength of photon, λ = 3.8 × 10-7 meters
Frequency of photon,
Thus, energy of photon,
= 5.2276 × 10-19 joules
The energy of a photon having a wavelength of 3.8 × 10-7 meters is 5.2275 × 10-19 joules.
