[1] Quantum Theory :
- Quantum Theory, Also Known As Quantum Mechanics, Is A
Fundamental Theory In Physics That Describes The Behavior
Of Matter And Energy At The Atomic And Subatomic Levels
- Quantization Of Energy: Planck Proposed That Energy Is
Quantized, Meaning It Can Only Exist In Discrete Amounts
Called "Quanta."
- This Revolutionary Idea Explained The Observed Behavior Of
Blackbody Radiation And Laid The Foundation For The
Development Of Quantum Theory.
- Quantum Superposition: Quantum Theory Allows For The
Existence Of Superposition, Where Particles Can Exist In
Multiple States Simultaneously.
- Max Planck's Groundbreaking Work On Quantum Theory
Revolutionized Our Understanding Of The Microscopic World
And Laid The Foundation For A New Branch Of Physics That
Continues To
Shape Our Modern Technological Advancements.
[2] Planck Constant :
- The Planck Constant (Symbolized As H) Is A Fundamental
Constant Of Nature And A Key Concept In
Quantum Mechanics.
- It Was Introduced By Max Planck As Part Of His Work On
Blackbody Radiation And Quantum Theory.
- The Planck Constant Has A Value Of Approximately
6.62607015 × 10^-34 Joule-Seconds (J·S) Or 4.135667696 ×
10^-15 Electron Volts-Seconds (Ev·S).
- The Planck Constant Also Plays A Significant Role In Other
Areas Of Physics, Such As The Study Of Condensed Matter,
Quantum Field Theory, And The Understanding Of Fundamental
Constants And Units Of Measurement.
- It Is Used To Calculate Quantities Such As The Energy Levels
Of Atoms And Molecules, The Wavelengths And Frequencies Of
Photons.
[3] Planck's Law Of Black Body Radiation :
- Planck's Law, Also Known As Planck's Radiation Law, Is A
Fundamental Principle In Physics That Describes The Spectral
Energy Distribution Of Electromagnetic Radiation Emitted By A
Black Body.
- Max Planck Derived This Law In 1900 As Part Of His Study On
Blackbody Radiation And It Played A Crucial Role In The
Development Of Quantum Mechanics.
- The Key Idea Behind Planck's Law Is That The Energy Emitted
Or Absorbed By A Black Body Is
Quantized.
- Meaning It Can Only Occur In Discrete Packets Or "Quanta" Of
Energy. This Concept Challenged Classical Physics, Which
Assumed That Energy Could Be Emitted Or Absorbed
Continuously.
- Planck's Law Provided A Crucial Foundation For The
Development Of Quantum Theory And Quantum
Mechanics.
[4] Planck Postulate :
- The Planck Postulate, Also Known As Planck's Quantum
Hypothesis, Is A Fundamental Assumption Made By Max Planck
In His Groundbreaking Work On Blackbody Radiation.
- This Postulate Was A Crucial Step Towards The Development
Of Quantum Theory And Marked A Departure From Classical
Physics.
- Planck Proposed That Energy Is Quantized And Can Only Exist
In Discrete Amounts.
- The Planck Postulate Was Introduced By Planck In 1900 As A
Theoretical Explanation For The Observed Spectrum Of
Radiation Emitted By A Blackbody.
- The Planck Postulate Played A Pivotal Role In The
Development Of Quantum Mechanics And The Understanding
Of The Behavior Of Matter And Energy At The Atomic And
Subatomic
Levels.
[5] Planck–Einstein Relation :
- Einstein-Planck Relation, Refers To The Fundamental
Relationship Between The Energy (E) Of A Photon And Its
Frequency (Ν).
- The Planck-Einstein Relation States That The Energy Of A
Photon Is Directly Proportional To Its Frequency, With The
Constant Of Proportionality Being Planck's Constant (H).
Mathematically,
It Is Expressed As
E = H
- The Planck-Einstein Relation Provided A Revolutionary
Understanding Of The Nature Of Light And
Energy.
- The Planck-Einstein Relation Has Broad Applications In
Various Areas Of Physics, Including The Study Of Atomic And
Molecular Spectroscopy, The Behavior Of Particles And
Radiation At The Quantum Level,And The Understanding Of
Phenomena Such As The Photoelectric Effect And The
Interaction Of Light With Matter.
