Question

explain black body radiation and photoelectric effect
class 11​

Answer 1

Answer:

Black Body Radiation means

1. an object that absorb all radiations falling on all wavelengths that is called as black body
2. It emissions is called as black body radiation
3. the concept of black body radiation is idealization as a perfect black body which do not exist in nature

Explanation:

Photo Photoelectric Effect means

1. it is the one of the phenomenon of Physics
2. this effect is based on the idea electromagnetic radiation is made up of a series of particles is called as Photon

Answer 2

Stefan-Boltzmann law, statement that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature. The law applies only to blackbodies, theoretical surfaces that absorb all incident heat radiation.
