Answer 1

You’ve just been involved in a traffic accident that leaves you stranded on the side of the road. Microwaves from the EM spectrum would be of the most use.

Explanation:

• Microwaves are a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter, with frequencies between 300 MHz and 300 GHz.
• Microwaves have a range of applications, including communications, radar and, perhaps best known by most people, cooking
• Microwave is a line-of-sight wireless communication technology that uses high frequency beams of radio waves to provide high speed wireless connections that can send and receive voice, video, and data information.
• Microwaves and radio waves are used to communicate with satellites.
• Microwaves pass straight through the atmosphere and are suitable for communicating with distant geostationary satellites, while radio waves are suitable for communicating with satellites in low orbit.
• Microwaves are widely used in modern technology, for example : in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, etc
