What does E in EM wave stand for?
EM waves stand for Electromagnetic waves.
Why antenna is a sensor of EM waves?
The transmitter sends out EM waves. EM waves are a carrier of energy and are produced by oscillating charges - usually caused by connecting metal to AC power supply. The waves travel through a medium and transfers its energy to the antenna which is basically a metal rod. The energy causes charges in the metal to oscillate at a certain frequency, controlled at the transmitting end. The charges oscillate to produce corresponding EM waves which can be detected/read as signals and turned into sound energy etc...
What does the e stand for in EM waves?

What type of em waves do cell phones depend on?

How do various kinds of em waves differ from each other?
There are two main types of EM waves. Magnetic waves and Electronic waves. They exist at orthogonal relationships with M waves and E waves at 90 degrees to each other.
What is energy and emitted in the form of EM waves?
Energy is the ability to do work or produce heat. Electromagnetic (EM) waves are a form of energy that travel through space as a combination of electric and magnetic fields. This type of energy is emitted by a variety of sources, including the sun and electronic devices.
What are the waves in the EM spectrum?
Radio waves are the longest lengthwise.
Do all EM waves transfer matter from place to place?
False. EM Waves do not transfer matter, they transfer energy.
