Which area of physics governs wireless communication?
a.
acoustics
b.
electricity
c.
electromagnetism
d.
astronomy
e.
thermodynamics

The correct answer is option C.  electromagnetism.

Explanation:

All text messages, photos and videos that we send through our wireless devices manage to transfer this data through a force called electromagnetism.

This force is one of the 4 natural forces that exist in nature and in it the electric fields interact with the magnetic fields.

Around us there is an invisible field called electromagnetic field, and this field can sometimes be disturbed by electromagnetic waves. These types of disturbances are what allow an electromagnetic wave to travel and send information.

The information will travel as a wave and will be received by an antenna, which will decode those waves in order to obtain the information that is being transported.
