Which color of light has the shortest wavelength in the visible spectrum?
A
Violet
B
Blue
C
Red
D
Green
Correct Answer: Option A — Violet
Explanation:
Violet light has the shortest wavelength in the visible spectrum, approximately 380-450 nanometers. Because shorter wavelengths carry more energy per photon, violet and blue light scatter more in the atmosphere, which is part of why the sky appears blue.
