In the visible light spectrum, violet light has the highest frequency. As you move from violet to red, the frequency of light decreases, while the wavelength increases. The sequence of colors in the visible spectrum, ordered from highest to lowest frequency, is as follows:
Violet - Indigo - Blue - Green - Yellow - Orange - Red
Violet light has the shortest wavelength and the highest frequency among the visible colors, while red light has the longest wavelength and the lowest frequency.
