The amount of energy carried by a single photon determines the type of radiation. Where do different types of radiation come from? All Objects in the universe emit (or give off) radiation photon by photon. The types of photons emitted by an object depend on the object’s temperature – hotter objects emit higher energy photons.

A single photon brings to the metal surface an energy of E( =hf using Planck’s equation for photon energy. Recall that only five years earlier Planck and the rest of the world refused to publicly accept that this equation was correct. Some of the photon energy is used to free the electron from the metal surface.

A particle of light, known as a photon, has an energy E. The energy of a single photon of visible light is tiny, barely enough to disturb one atom; we use units of “electron-volts”, abbreviated as eV, to measure the energy of photons.

The energy of a single photon is E = hf. The frequency of the photon is related to its wavelength by = c/ . Solution . At an efficiency of 2.1%, the light energy emitted per second by a sixty-watt bulb is (0.021)(60.0 J/s)=1.3 J/s. The energy of a single photon is . E = hc/ (6.63×10-34Js)(3×108 m/s)/555×10-9 nm = 3.58×10-19 J

A monochromatic light source emits photons of a single frequency. According to Equation 29.2, the energy, E, of a single photon is related to its frequency, f, by the relation , where h is Planck's constant. The photons emitted by a source of light do not all have the same energy.

E = hc/λ (this energy corresponds to the energy of one photon; the energy given in this problem is for one mole of photons so we will change this after we change the units from kJ to J). 508 kJ/mol photons = 8.44 x 10-19 J/photon. E = hc/λ. Rearranged: λ = hc/E. λ = = 236 x 10-9 m or 236 nm
