GK QUESTION#3140

Statement I: The Dirac equation, derived in 1928, combines quantum theory and special relativity to describe electrons moving at relativistic speeds. Statement II: Bernoulli's equation is used to describe the behavior of electrons at relativistic speeds.

B. Only Statement I is true

Show ExplanationHide Explanation

Explanation

Dirac’s 1928 equation combined quantum mechanics with special relativity in a theory of the electron. Bernoulli’s equation describes idealised fluid flow, not the relativistic electron wave equation. Only Statement I is true.
