question 21 of 33
early experiments with light were understood by explaining the behavior of light in terms of waves. which experimental result required considering the particle nature of light?
a. the refraction of light through a prism
b. the interference of light traveling through thin films
c. the dark - and - light pattern seen with a diffraction grating
d. the ultraviolet catastrophe of blackbody radiation

Explanation:

The ultraviolet catastrophe of black - body radiation couldn't be explained by wave theory. Planck's solution to this problem introduced the concept of quantized energy, which led to considering the particle nature of light (photons). Refraction, interference, and diffraction can be well - explained by the wave nature of light.

Answer:

D. The ultraviolet catastrophe of blackbody radiation
