AP PSYCHOLOGY

Detailed explanation-1: -To quickly summarize: Hue = wavelength, Brightness = the amplitude of the wave or the amount of photons hitting the eye.

Detailed explanation-2: -Most sources of visible light contain energy over a band of wavelengths. Hue is the wavelength within the visible-light spectrum at which the energy output from a source is greatest.

Detailed explanation-3: -The color or hue of light depends on its wavelength, the distance between the peaks of its waves. The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness depends on light wave amplitude, the height of light waves.

Detailed explanation-4: -Intensity (also called chroma or saturation) is the brightness or dullness of a color.

Detailed explanation-5: -Hue is determined by the dominant wavelength of the visible spectrum. It is the attribute that permits colors to be classified as red, yellow, green, blue, or an intermediate color. Saturation pertains the amount of white light mixed with a hue.
