Question

Classical electromagnetic theory predicted that the energy radiated by a blackbody would became infinite as the wavelength became shorter. What was the contradiction between observation and this result called?

a) A quantum theory.
b) The photoelectric effect.
c) The wave-particle duality.
d) The ultraviolet catastrophe.

Answer 1

d) The ultraviolet catastrophe.

Step-by-step explanation:

-Ultraviolet catastrophe was a 19th century prediction that an ideal black body at thermal equilibrium will emit radiation in all frequency ranges.

-This Classical electromagnetic theory is also called the Rayleigh–Jeans catastrophe.
