Re: Photon
Photons are essentially packets of energy. The photoelectric effect basically states that a certain amount of energy is required to emit an electron from a metal (work function). If the photon's energy equals or exceeds the work function then the photon will transfer it's energy to the electron so that the electron can be emitted.
Re: Photon [ENDORSED]
A photon is essentially a packet of electromagnetic energy. Photons are unique in that they are both, a particle and a wave. A photon must have enough energy (high enough frequency) in order to remove an electron from a metal. In other words, the photon's energy must be greater than or equal to the threshold energy of the metal, which is the amount of energy required to remove an electron. The threshold energy varies by metal.

Re: Photon
A photon is a packet of energy, representing a way in which light acts as a particle.
A photon carries energy proportional to its frequency and has zero mass.

Re: Photon
Photons don't necessarily have "size" as we think about it on a macroscopic scale. They are just packets of energy.
Re: Photon
I believe that a photon does not have a specific size. It carries energy, momentum,and frequency, but is simultaneously a particle and a wave.
