Question

A cell phone company relies on which kind of waves in order to provide service for its customers? ultraviolet waves infrared waves gamma rays microwaves

Answer 1

The correct answer is Microwaves

Step-by-step explanation:

Among all the waves mentioned Micro-waves has the highest wavelength which helps it to transfer data along longer distances

Answer 2

microwaves

Step-by-step explanation:

Electromagnetic waves consist of waves of different wavelengths. Among the choices given, waves are ordered for increasing wavelengths as follows:

gamma rays --> ultraviolet waves --> infrared waves --> microwaves

So, microwaves are the waves with the longer wavelength among the given choices. This is the reason why they are used by the cell phone companies: in fact, since they have longer wavelengths, microwaves can travel longer distances without being absorbed by objects or obstacles, and so they are more reliable for broadcasting and telecommunications.
