SUMMARY
A photon is defined as a packet of electromagnetic energy, quantized light energy that does not possess mass but has momentum due to its energy. The relationship between energy and momentum is described by the equation E=pc. Photons travel at the speed of light, which is intrinsic to their nature as light particles. Their wavelength can be calculated using the De Broglie wave equation, λ=h/p, where h represents Planck's constant and p denotes momentum.
