Answer 1

A boy uses a GPS device to locate his missing friend in a crowded area; the system primarily uses microwaves to track the location.

Explanation:

GPS (Global Positioning System) technology relies on signals transmitted from satellites orbiting the Earth. These signals are a form of electromagnetic radiation, specifically microwaves. Microwaves are able to pass through the atmosphere and reach the ground with minimal interference, making them ideal for reliable global positioning and navigation systems.
