Question

Cell phones communicate by means of waves. What are the primary characteristics of those waves that make them suitable for use in cell-phone networks?

A. Long wavelengths
B. Low Frequencies
C. Short Wavelengths
D. High Speed

Answer 1

Answer: Long wavelengths

Step-by-step explanation:

Mobile phones communicate by transmitting radio waves through a network of fixed antennas called base stations. Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, can neither break chemical bonds nor cause ionization in the human body.
