Which color of the spectrum has the shortest wavelength?

Which color of the spectrum has the shortest wavelength?

• A. Violet
• B. Red
• C. Yellow
• D. Indigo

Answer: (A)

Violet is the color of the spectrum that has the shortest wavelength. The visible light spectrum is arranged from red to violet, with red having the longest wavelength and violet having the shortest. In terms of wavelength, violet light ranges approximately from 380 to 450 nanometers, while red light ranges from about 620 to 750 nanometers. This fundamental characteristic is important in understanding light and color perception, as the shorter wavelengths of violet light contribute to its higher energy compared to the longer wavelengths of other colors, such as red or yellow.
