Question

As we move through the visible spectrum, red to violet (right to left in the image), the wavelength __________ and the frequency ____________.

A) increases; decreases

B) increases; increases

C) decreases; increases

D) decreases; decreases

Answer 1

As we move through the visible spectrum, red to violet (right to left in the image), the wavelength decreases and the frequency increases. The correct option among all the options that are given in the question is the third option or option "C". I hope this answer helps you and you will understand the solution also. 

Answer 2

Answer;

C) decreases; increases

Explanation;

• As we move through the visible spectrum, red to violet (right to left in the image), the wavelength decreases and the frequency increases.
• Electromagnetic spectrum comprises of electromagnetic waves arranged in the order of increasing or decreasing frequency and wavelength.
• These electromagnetic waves includes; radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays.
• In electromagnetic spectrum as you move from left to right, that is from the radio waves towards the gamma rays, the wavelength decreases as the frequency increases; while from gamma rays towards the radio waves the wavelength increases while the frequency decreases.
