b. None of these technologies use lower-frequency microwaves.
c. None of these technologies use higher-frequency microwaves.
d. None of these technologies use infrared waves.
e. The radiation emitted by some wireless local area networks has the shortest wavelength of all the technologies listed above.
f. All these technologies emit waves with a wavelength in the range 0.10 to 10.0 cm.
g. All the technologies emit waves with a wavelength in the range 0.01 to 10.0 km.

Answer :

Answer:

The answer is "c,d,e, and g".

Explanation:

The correct choices can be defined as follows:

  • Higher-frequency microwaves aren't used in any of these systems.
  • Infrared waves aren't seen in each of these technologies.
  • Its shortest wavelength of all of the technologies listed is the above radiation generated by certain wireless networks.
  • These devices all produce waves of wavelengths ranging from 0.10 to 10.0 cm.
