For me the answer is
d) wavelength
this is because the wavelegths of the light are responsible for different colors of light. Amplitude is just responsible for the intensity of light. On the other hand different wavelenghths of lights are distinguished by the different colors they aquire.
Hope it helps :)

Answer;

D. wavelength

Explanation;

  • Visible light is a part electromagnetic spectrum which is made up of electromagnetic waves of varying frequency and wavelengths.
  • Wavelength is the distance between two successive crests or troughs in a transverse waves, or the distance between two successive rarefactions or compression in a longitudinal wave.
  • Visible light waves are of different frequencies and wavelengths. They are called visible lights because human beings can detect them and are also sensitive to them. The wavelength of visible light waves determines the color of visible light.
