Which color of light has the highest frequency?

• A. Red
• B. Green
• C. Violet
• D. Blue

Answer: (C)

Violet light has the highest frequency among the colors listed. The electromagnetic spectrum consists of a range of colors, each defined by its wavelength and frequency. As you move from red to violet in the visible spectrum, the wavelengths decrease, and the frequencies increase. Violet light sits at the shorter wavelength end of the visible spectrum, which corresponds to higher energy and higher frequency. This relationship is due to the formula that relates the speed of light (which is constant) to wavelength and frequency: as wavelength decreases, frequency must increase to maintain this constant product. Hence, within the visible spectrum, violet light has the highest frequency, making it the correct answer to the question.
