Hello everyone. Welcome to my newsfell. So in this video, I am going to tell you about how plans constant value was determined. It was observed as early as 1905 that most metals under influence of radiation emitted electrons. This phenomenon was terminated based photoelectric emission. The true study of the photoelectric emission is like this that the emission process depends strongly on frequency of radiation. For each metal that exists the critical frequency such that the light of lower frequency is unable to lower electrons
