Which of the following colors of visible light has the longest wavelength?
A
Blue
B
Green
C
Yellow
D
Red
E
Violet
Explanation: 

Detailed explanation-1: -Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

Detailed explanation-2: -The frequency of light decreases from violet to red, hence, wavelength increases from violet to red and the lowest frequency, we know that wavelength is inversely proportional to the frequency. It means when frequency increases then wavelength decreases, and when wavelength increases the frequency decreases.

Detailed explanation-3: -Visible Light Spectrum From longest to shortest wavelength, they are: red, orange, yellow, green, blue, indigo, and violet.
