How is electromagnetic energy transmitted?
Electromagnetic radiation is energy transmitted at a fixed velocity through sinusoidally varying electric and magnetic fields. The energy of a photon is directly proportional to the frequency of the radiation, with a constant of proportionality called Planck’s constant.

What is the direction of propagation of electromagnetic wave?
The direction of propagation of the electromagnetic wave is always perpendicular to the plane in which E and B lies. So, the direction of the propagation of the wave, C =E×B.
What is being transferred by a wave?
Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.
How does longitudinal wave propagate?
Compressional waves (longitudinal, primary, P-waves of earthquake seismology) are the fastest of all seismic waves. They propagate by compressional and dilatational uniaxial strains in the direction of wave travel through solid, liquid, and gas media.
What are transmission waves?
Transmission of waves occurs when waves pass through a given point or medium. Light waves are transmitted through transparent materials (may be clear or colored material such as filters) that allow most of the light that strikes them to pass through them. Only a small amount of light is reflected or absorbed.
What is transferred from place to place by waves?
A wave is a disturbance that transfers energy from one place to another without transferring matter. Waves transfer energy away from the source, or starting place, of the energy.
How is energy transferred in transverse waves?
The particles involve vibrate around in compressions and rarefractions which would be perpendicular to the oscillation. Energy transfer is work done and work done is force x displacement. The particles get displaced while exerting a force hence energy is transferred.
How would you describe the motion of a longitudinal wave?
A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. Longitudinal waves are always characterized by particle motion being parallel to wave motion. A sound wave traveling through air is a classic example of a longitudinal wave.
Which quantity is transmitted with propagation of longitudinal waves through a medium?
energy
With propagation of longitudinal waves through a medium the quantity transmitted is. Propagation of longitudinal waves through a medium leads to transmission of energy through the medium.
What is transmission process?
: the act or process of sending electrical signals to a radio, television, computer, etc. : something (such as a message or broadcast) that is transmitted to a radio, television, etc. : the act or process by which something is spread or passed from one person or thing to another.
What is electromagnetic propagation?
Let’s start with the very basics. What is Electromagnetic Wave Propagation? Electromagnetic Waves also called Electromagnetic Radiations are basically defined as superimposed oscillations of an Electric and a Magnetic Field in space with their direction of propagation perpendicular to both of them.
How are electromagnetic waves propagated from the transmitter antenna to receiver antenna?
The electromagnetic waves are propagated from the transmitter antenna to the receiver antenna in the following ways: Ground waves: When the electromagnetic waves are propagated along the surface, the propagation is known as ground wave propagation.
What is the difference between ground wave and space wave propagation?
Ground waves: When the electromagnetic waves are propagated along the surface, the propagation is known as ground wave propagation. Space waves: When the electromagnetic waves propagate from the transmitter antenna to the receiver antenna without any reflection or refraction, the propagation is known as space wave propagation.
How do electromagnetic waves travel through a medium?
The atoms absorb the wave energy, undergo vibrations and pass the energy by re-emission of EM of the same frequency. The optical density of the medium affects the propagation of EM waves. Waves take many routes on their way to reach the receiver.
