How many types of nature of light

1.	How many types of nature of light
Answer» The emission of free electrons from a metal surface when the light is shone on it, it is called the photoemission or the photoelectric effect. This effect led to the conclusion that light is made up of packets or quantum of energy. Now the question was whether the light quantum theory was indicative of the particle nature of light. Einstein already associated the light quantum with momentum. This strongly supported the particle nature of light and these particles were named\xa0photons. Thus, the\xa0wave-particle duality\xa0of light came into the picture.Photoelectric Emission 2
