Answer 2

A  type of electromagnetic wave a computer scanner use is high-frequency radio waves.

The concept of wave-particle dualism was developed and key milestones in the understanding of the fundamental nature of light and electrons were made possible by research into the photoelectric effect.

What is the use of a computer scanner?

A scanner is a tool that digitizes information by scanning or taking a photo of a document and displaying it on a computer screen. It makes it easier for both teachers and students to copy instructional resources like documents and pictures, as well as to take and preserve pictures.
