• B. length of the wave.
• C. amplitude of the wave.
• D. dilation of the pupils.

Answer: (B)

Verified step by step guidance

1. Begin by understanding the concept of color perception in psychology, which involves how humans perceive different wavelengths of light as different colors.
2. Recognize that the perception of color is primarily determined by the wavelength of light. Different wavelengths correspond to different colors in the visible spectrum.
3. Consider the role of amplitude in light waves, which affects the brightness or intensity of the color rather than the color itself.
4. Understand that pupil dilation can affect the amount of light entering the eye but does not directly determine the color perceived.
5. Conclude that the length of the wave, or wavelength, is the key factor in determining the color perceived by the human eye.
