Which of the following colour of white light has the maximum wavelength?
-
A.
Green
-
B.
Red
-
C.
Violet
-
D.
Orange
Correct Answer:
B. Red
Explanation:
White light is composed of a spectrum of seven constituent colors: violet, indigo, blue, green, yellow, orange, and red. Each color possesses a specific wavelength, and when ordered from shortest to longest wavelength, they follow the acronym VIBGYOR. Red light sits at the end of this visible spectrum with the longest wavelength, ranging approximately between 620 and 750 nanometers. Because it has the maximum wavelength, red light also experiences the least amount of deviation or scattering when passing through a medium like a prism. Therefore, among the choices provided, red is the correct answer.
