In particular, the photon model accounted for the frequency dependence of light's energy, and explained the ability of matter and radiation to be in thermal equilibrium.he energy of a system that emits a photon is decreased by the energy of the photon as measured in the rest frame of the emitting system, which may result in a reduction in mass in the amount. Similarly, the mass of a system that absorbs a photon is increased by a corresponding amount.
Responding to the changes, the Finnish company started churning out both sophisticated multimedia handsets as well as low-end devices. The year 2001 saw the company launching the Nokia 7650, its first phone to feature a built-in camera. It was also the first to sport a full color display.
