how do home computer scanners use electromagnetic waves? a. the waves make objects brighter, making them easier to see. b. the waves are absorbed by objects, making them warmer. c. the scanners change information received into modified radio waves. d. the waves are absorbed or reflected to capture images or information.

Explanation:

Home - computer scanners work by shining light (an electromagnetic wave) on an object. The light is either absorbed or reflected by different parts of the object. The scanner's sensors detect these variations in absorption and reflection to capture an image or information about the object.
