Two models were developed to explain what light is, the photon model, which depicts light as a particle, and the wave model. In the field of quantum mechanics it is now recognized that light is both a particle and a wave (sometimes called a wavicle).
The particle model of light entails that light consists of tiny packages of energy called photons. Because light is an electromagnetic wave the model is a part of the general model for electromagnetism. This model is called Quantum Electrodynamics, or QED in short.
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
photon
the mass of a photon is zero
You need to know the photon's frequency or wavelength. If you know the wavelength, divide the speed of light by the photon's wavelength to find the frequency. Once you have the photon's frequency, multiply that by Planck's Konstant. The product is the photon's energy.

tata photon plus is ratan tata and Javed Siddiqui is houner of PHoton whiz..............
No, a photon is not time travelling
No. A photon is a particle of light. It is massless.

the mass of a photon is zero
You need to know the photon's frequency or wavelength. If you know the wavelength, divide the speed of light by the photon's wavelength to find the frequency. Once you have the photon's frequency, multiply that by Planck's Konstant. The product is the photon's energy.
No, it could not. A blue photon carries more energy than a red photon, since the blue photon's frequency is higher. That means one red photon wouldn't deliver enough energy to the atom to give it the energy to emit a blue photon.
