Question

The electromagnetic spectrum is arranged by the frequencies and
wavelengths


of electromagnetic radiation. The waves of energy that make up the spectrum have many uses in our everyday lives. Some of these include
communication


, cooking, preservation of food, and healthcare. Even though there are many different types of waves, there is only one small part of the spectrum that humans can see. This is the
portion of the spectrum. It consists of the colors red, orange, yellow, green, blue, indigo, and violet, and when combined, these colors create white light.
amplitude
X-ray
visible light
manufacturing

Answer 1

Answer: visible light.

Filled sentence: "This is the visible light portion of the spectrum."

(Explanation: visible light is the small part humans can see — red through violet. X-rays are not visible, amplitude is a wave property, and manufacturing is unrelated.)
