Final answer:
The electromagnetic spectrum encompasses various types of radiation ordered by decreasing wavelength (radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays). Light waves of blue, yellow, and red are arranged from shortest to longest wavelength and from highest to lowest frequency inversely.
Step-by-step explanation:
The different parts of the electromagnetic spectrum can be ordered by decreasing wavelength, increasing frequency, or increasing energy. In order of decreasing wavelength (which simultaneously means increasing frequency and energy), the electromagnetic spectrum consists of: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
For the colors of light listed, the order according to wavelength from shortest to longest would be: blue, yellow, red. Conversely, according to frequency from lowest to highest, it would be: red, yellow, blue.
One important concept to understand is that wavelength and frequency are inversely proportional to each other. This means that as the wavelength of an electromagnetic wave increases, its frequency decreases. This relationship is a fundamental characteristic of all waves in the electromagnetic spectrum.
