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.
The KODAK camera introduced in 1888 was the first box camera to become widely adopted by the public and its design became the archetype for box camera designs introduced by many different manufacturers. The Kodak introduced in 1888 first commercially successful box camera for roll film -- the advertising slogan being You press the button â we do the rest. 2  The Kodak Brownie, a long lasting series of classical box cameras using roll film. 3  The Ansco panda was designed to compete directly with the Brownies.
