In 1928, which equation was derived and combines quantum theory and special relativity to describe the behaviour of an electron moving at a relativistic speed?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Dirac equation.
In 1928, Paul Dirac derived the Dirac equation, which combines quantum theory and special relativity to describe the behavior of an electron moving at relativistic speeds. The Dirac equation accounts for the relativistic effects and predicts the existence of antimatter. It successfully merges the principles of quantum mechanics with special relativity, providing a more accurate description of electron behavior and leading to significant advancements in quantum field theory and particle physics.
