• D. Yellow

Answer: (B)

Verified step by step guidance

1. Recall that visible light is a portion of the electromagnetic spectrum with wavelengths approximately between 400 nm and 700 nm.
2. Understand that the color of visible light is directly related to its wavelength: red light has the longest wavelength (~700 nm), and violet light has the shortest wavelength (~400 nm).
3. Recognize that as wavelength decreases, the energy of the light increases, so violet light has higher energy and shorter wavelength compared to red, green, or yellow light.
4. Identify the order of colors from longest to shortest wavelength as: red, yellow, green, blue, and violet.
5. Conclude that violet corresponds to the shortest wavelength among the given options.
