- Which of the following is TRUE regarding reflection and refraction? a. Reflection can be explained by the particle nature of light while refraction cannot. b. Refraction can be explained by the wave nature of light while reflection cannot. c. Reflection and refraction can be explained by both the wave and particle nature of light. d. Reflection and refraction can only be explained by the wave nature of light. The perception of color does not correspond to a unique set of wavelengths. The human eye distinguishes several hundreds of colors and shades. The eye has only three separate types of visual signals. So the different signal perceptions of colors are combinations of these three visual signals. Perception of colors depends upon the relative stimulation of the three color sensitive cells in the retina of the eye. What are the requirements for perceiving colors? a. Eye and light b. Eye, object, and light c. Eye, light, and shadow d. Eye, light, and mediumarrow_forwardWhich one of the following experiments is the justification for the wave theory of light? a.
