Question

question 27 of 33 which statement below best describes the evolution of our understanding of light and matter? a. light was initially understood as a wave, but experimental results indicated that it also has a particle nature. b. both electrons and light were initially understood to be particles, but experimental results indicated that both also have a wave nature. c. both electrons and light were initially understood as waves, but experimental results indicated that both also have a particle nature. d. electrons were initially understood as waves, but experimental results also indicated a particle nature.

Explanation:

Initially, light was thought of as a wave. However, phenomena like the photoelectric effect showed that light also has particle - like behavior (photons). Electrons were first considered particles, but the double - slit experiment demonstrated their wave nature. Option A correctly describes the evolution of our understanding of light.

Answer:

A. Light was initially understood as a wave, but experimental results indicated that it also has a particle nature.
