Question

fill in the blank question
in this diagram, the parts of the electromagnetic spectrum are arranged in order of decreasing
need help? review these concept resources.

Explanation:

The electromagnetic spectrum is arranged from left to right with decreasing wavelength. As wavelength decreases, frequency (using \(c = \lambda f\) where \(c\) is the speed of light) increases. But the key visual in the diagram is the scale on the bottom which shows values like \(10^{3},1,10^{-3}\) etc., representing wavelength. So the arrangement is based on wavelength.

Answer:

wavelength
