Question

complete the following paragraph to explain the electromagnetic spectrum. the electromagnetic spectrum is composed of all forms of electromagnetic radiation. visible light is one example of electromagnetic radiation. all electromagnetic radiation travels at the speed of light, but different types of electromagnetic radiation differ in wavelength, frequency, and energy. as wavelength increases, frequency and energy decrease, and as wavelength decreases, frequency and energy increase. radio waves and microwaves have the longest wavelengths, and x - rays and gamma rays have the shortest wavelengths.

Explanation:

Step1: Recall electromagnetic - spectrum properties

Electromagnetic radiation travels at the speed of light.

Step2: Understand wavelength - frequency - energy relationship

As wavelength increases, frequency and energy decrease. Radio waves and microwaves have long wavelengths, while x - rays and gamma rays have short wavelengths.

Step3: Fill in the blanks
