B Correct answer
Explanation

Different colors of light correspond to different frequencies and wavelengths in the electromagnetic spectrum. Red light has the longest wavelength (approximately 700 nm) and lowest frequency, while violet has the shortest wavelength (approximately 400 nm) and highest frequency. This variation in frequency is what our eyes perceive as different colors.
