What is photon wavelength?! What is photon wavelength exactly? I know that the energy of a photon is E = hc/lambda, where frequency = c/lambda and lambda is the wavelength. So, what determines the wavelength of a photon? Is it the distance an electron falls from the conduction band back down...

Photons are stated as having no mass. Therefore, they cannot create a gravitational field. They may be able to create a gravitational "wave" perpendicular to their path, perhaps.

Correct, an electron has both mass and charge. When talking about energy, a conversion is 1eV x (1.6E-19 Joules/ 1eV), where eV stands for electron Volt. This is equal to the amount of kinetic energy gained by the electron when it accelerates through a one volt potential difference. Now, the...
