H in photoelectric effect
WebbRadiation The photoelectric effect. The photoelectric effect is caused by the absorption of electromagnetic radiation and consists of electron ejection from a solid (or liquid) surface, usually of a metal, though nonmetals have also been studied. In the case of a gas, the term photoionization is more common, though there is basically little difference … Webb광전 효과 (光電效果, 독일어: photoelektrischer Effekt, 영어: photoelectric effect )는 금속 등의 물질이 한계 진동수 (문턱 진동수)보다 큰 진동수를 가진 (따라서 높은 에너지 를 가진) 전자기파 를 흡수했을 때 전자 를 내보내는 현상이다. 이 때 방출되는 전자를 광전자라 ...
