Question & Answer
Choose the Best Answer
The photoelectric effect demonstrated the particle nature of light.
Black-body radiation was explained using classical wave theory.
The Bohr model introduced quantized orbits for electrons.
Quantum mechanics was fully developed in the early 19th century.
The uncertainty principle was a fundamental concept introduced by Heisenberg.
Understanding the Answer
Let's break down why this is correct
The photoelectric effect showed that light can behave like tiny particles called photons. Other options are incorrect because The idea that black‑body radiation could be explained by ordinary wave theory is a common mistake; Many think quantum mechanics began in the early 19th century, but the main ideas only appeared in the early 20th century with work by Planck, Einstein, Bohr, and Heisenberg.
