Light travels in the form of waves, and these waves affect three aspects of our visual world. Describe, in detail, the three physical characteristics of light waves, and how each affects a specific psychological dimension of our visual experience
What will be an ideal response?
Answer: A good answer will include the following key points.
• The physical properties of light are wavelength, intensity or amplitude, and complexity.
• These physical properties correspond to psychological dimensions of our response.
• Wavelength corresponds to hue, or our perception of color, with shorter waves appearing as violet or blue and longer ones as orange and red.
• Intensity, or amplitude, corresponds with our perception of brightness.
• Complexity corresponds to our perception of saturation, with a mixture of wavelengths seen as duller and paler and a narrow band of wavelengths seen as pure, more colorful, or completely saturated.
