Question

which pair of phenomena both support the particle model of light?
a. the photoelectric effect and constructive interference
b. diffraction and interference
c. blackbody radiation and the photoelectric effect
d. blackbody radiation and diffraction

Explanation:

The photoelectric effect shows that light behaves as particles (photons) when it ejects electrons from a metal surface. Black - body radiation can be explained using the concept of quantized energy (photons), which also supports the particle model of light. Diffraction and interference are phenomena that support the wave - model of light, and constructive interference is part of the wave - behavior of light.

Answer:

C. Blackbody radiation and the photoelectric effect
