D Correct answer
Explanation

Different colors of light correspond to different wavelengths and different frequencies. These two properties are inversely related through the equation c = λf (where c is the speed of light, λ is wavelength, and f is frequency). Red light has longer wavelength and lower frequency, while violet light has shorter wavelength and higher frequency. Therefore, both wavelength and frequency differ across different colors.
