• A. Frequency
• B. Phase
• C. Amplitude
• D. Speed

Answer: (A)

Verified step by step guidance

1. Understand that visible light is an electromagnetic wave characterized by properties such as frequency, wavelength, amplitude, phase, and speed.
2. Recall that the color we perceive from visible light depends on the wavelength or frequency of the light, as different frequencies correspond to different colors in the visible spectrum.
3. Recognize that amplitude relates to the brightness or intensity of the light, not its color.
4. Note that phase is related to the position of the wave in its cycle and does not affect the color perception.
5. Understand that the speed of light in a vacuum is constant and does not determine color; instead, frequency (or wavelength) is the key property that determines the perceived color.
