In this video we have discussed about the photoelectric effect (part1).
The photoelectric effect is the emission of electrons when electromagnetic radiation such as light hits a material. Electrons emitted in this manner are called photoelectron.
The photoelectric effect was first observed in 1887 by Heinrich Hertz during experiments with a spark gap generator. After many scientist try to explain various aspect of photoelectric effect.
In this video we discussed about (1)work function (2)stopping potential (3)threshold frequency (4)maximum kinetic energy of electron etc
Topic covered-1)photoelectric effect was discovered by
2)photoelectric effect was explained by
3)photoelectric effect equation
4)photoelectric effect equation derivation
5)derive einstein's photoelectric equation class 12
6)derive einstein photoelectric equation class 12
7)what is photoelectric effect class 11
8)what is photoelectric effect
9)What is photoelectric effect class 11
10)What is Einstein's photoelectric effect
11)What is photoelectric effect class 12
