Quantum physics: The photoelectric effect What is the photoelectric effect? The photoelectric effect is when a clean metal surface emits electrons after light‚ especially ultraviolet‚ has been shone on at it. This happens because of a process called photoelectric emission whereby a single photon package of electromagnetic energy‚ called a quantum‚ is absorbed by metal surfaces. This energy is then transferred to one single electron which can then be released by the metal and that released electron

The bystander effect was initially observed in adults (Darley & Latané‚ 1968)‚ who found themselves either alone or in a group in a waiting room when they noticed the room began to fill with smoke. It was found that by the 6-minute mark 75% of people who were alone reported the smoke; however‚ when people were in groups in the waiting room only

entitled the Halo Effect. With the Halo Effect comes just the opposite‚ we as individuals judge others subconsciously upon their looks and other positive qualities we perceive‚ in turn making judgements about who they are in regards to a few characteristics. In this paper I will explain in detail what the Halo Effect is‚ how it affects our judgment in certain situations‚ reference studies where this effect has been proven‚ as well as how to counteract this effect.
