Which of the following is true about green light? a) It has a greater frequency than red light and blue light. b) It has a smaller frequency than red light and blue light. c) It has a greater frequency than red light but a smaller frequency than blue light. d) It has a smaller frequency than red light but a larger frequency than blue light.

c) It has a greater frequency than red light but a smaller frequency than blue light.

Explanation:

According to the relation:

c = frequency * Wavelength

The higher the frequency, the lower the value of wavelength

The order of wavelength is:

Violet < Indigo < Blue < Green < Yellow < Orange < Red

Stated above, frequency is inversely proportional to the wavelength. Thus, the order of wavelength is:

Violet > Indigo > Blue > Green > Yellow > Orange > Red

Thus,

Green light has lower frequency than blue light and higher than red light.
