The energy of a photon of green light with a frequency of 5.76 x 10¹⁴ s⁻¹ is 45.5 x 10⁻⁴⁷ J
What is Energy of a Photon ?
The energy of a single photon is: hν or = (h/2π)ω where h is Planck's constant: 6.626 x 10⁻³⁴Joule-sec.
One photon of visible light contains about 10-19 Joules the number of photons per second in a beam. where P is the beam power (in watts).
Formula to calculate energy of photon ;
E = hv
v = c/λ
= 3.00 x 10⁸ m/s / 4.3 x 10²⁰ s⁻¹
= 6.9 x 10⁻¹³ m
Now,
E = hv
= 6.626 x 10⁻³⁴ x 6.9 x 10⁻¹³
= 45.5 x 10⁻⁴⁷ J
Hence, The energy of a single photon is: hν or = (h/2π)ω where h is Planck's constant: 6.626 x 10⁻³⁴Joule-sec.
