Raleigh Jean predicted behavior of black body radiations, this predictions came to conclusion that:
Correct answer: C. Failed to explain ultraviolet region
- A. Explained with quantum theory
- B. Explained well by mathematical treatment
- C. Failed to explain ultraviolet region
- D. Used Einstein's theory of relativity
Explanation
Raleigh-Jean did make predictions about black body radiation, but those predictions couldn't explain the behavior in the ultraviolet (UV) region. It was Max Planck who later developed a new theory, known as quantum theory, which successfully explained the UV behavior.

About Quantum Theory and Radiation
Quantum theory treats electromagnetic radiation as packets of energy called photons, with energy proportional to frequency through E equals hf. The topic covers Planck's hypothesis, photon momentum, the photoelectric effect, threshold frequency, work function and wave particle duality, distinguishing quantised energy exchange from classical continuous radiation.
