What are the drawbacks of classical free electron theory?
Drawbacks of classical free electron theory 1) It fails to explain the electric specific heat and the specific heat capacity of metals. 2) It fails to explain superconducting properties of metals. 3) It fails to explain new phenomena like photo-electric effect, Compton effect, Black body radiation, etc.
Which theory can be adopted to rectify the drawbacks of classical theory?
Hence Quantum theory is used to rectify the drawbacks of classical theory.
What are some of the problems with classical physics?
The Problems with Classical Physics. Electromagnetic waves like light are made up of particles we call photons. Einstein, based on Plank’s formula, hypothesized that the particles of light had energy proportional to their frequency. The new idea of Quantum Mechanics is that every particle’s probability…
What problems with classical physics led to the development of quantum mechanics?
The problems with classical physics led to the development of Quantum Mechanics and Special Relativity. Some of the problems leading to the development of Quantum Mechanics are listed here. Black Body Radiation:Classical physics predicted that hot objects would instantly radiate away all their heat into electromagnetic waves.
What are the laws of physics based on?
By the late nineteenth century the laws of physics were based on Mechanics and the law of Gravitation from Newton, Maxwell’s equations describing Electricity and Magnetism, and on Statistical Mechanics describing the state of large collection of matter.
Why is Planck’s constant so important to modern physics?
If you look at most of the “equations” above, you will find Planck’s constant, h. This is the trademark of “modern physics.”. The failure of classical physics to explain blackbody radiation, the photoelectric effect, and the hydrogen atom ultimately demolished the foundations of classical physics.
