Direction finding depends on a process of triangulation. Ship's navigators used to do this by sighting three points on the shore and plotting the angles on a chart. Then this method was adapted by using radio transmitters, and with a receiver that has a sharply defined angle of acceptance, you can do the same thing. Nowadays with satellites the system of GPS (Global Positioning System) has evolved. The receiver detects the angles of three satellites and works out the position automatically.

What is the most common type of wave?
The most common type of wave is the transverse wave, where the oscillations of the wave are perpendicular to the direction of energy transfer. Sound waves, electromagnetic waves, and ocean waves are examples of transverse waves.
What is the definition of electromagnetic wave?
An electromagnetic wave is a type of energy wave that consists of vibrating electric and magnetic fields propagating through space. These waves carry energy and information through a vacuum or a medium, and they travel at the speed of light. Examples of electromagnetic waves include radio waves, microwaves, visible light, X-rays, and gamma rays.
A wave whose energy travels the same way as it was transferred?
A transverse wave is a type of wave where the disturbance moves perpendicular to the direction of energy transfer. This means that the energy travels in the same direction as it was transferred. Examples of transverse waves include light waves and electromagnetic waves.
Why is light considered an electromagnetic wave?
When it was determined that light exhibits all of the properties of wave motion, including refraction, reflection, diffraction, and dispersion, and that its speed is exactly determined by the electrical characteristics of the medium through which it propagates, just like radio, heat, ultraviolet radiation, X-rays, and gamma rays, and as predicted by the wave equation that Maxwell derived from the properties of electricity and magnetism, it then began to dawn on cutting-edge researchers that light is also an electromagnetic wave. In short, the answer to the question "why" is: Because it IS one.
Wave that can travel through an empty space?
An electromagnetic wave, such as light or radio waves, can travel through empty space because they do not require a medium to propagate. This is due to their unique properties of electric and magnetic fields oscillating in tandem at right angles to each other.
What type of energy does light wave transmit?
Electromagnetic energy
Do All emitters transmit either a continuous wave or a pulsed waveform?
Yes, all emitters transmit either a continuous wave or a pulsed waveform. Continuous wave emitters transmit a continuous stream of electromagnetic waves, while pulsed waveform emitters transmit short bursts of electromagnetic waves with periods of rest in between.
Is it possible to transmit electricity as electromagnetic waves?
Well, when you transmit something as an electromagnetic wave, it is no longer an electric current, since an electromagnetic wave doesn't involve movement of charges. However, you can convert electrical energy into an electromagnetic wave, transfer that, and then convert it back to an electric current at the receiving end.
Which type of hearing aids are required by persons on the surface of moon?
The hearing aids which transmit and detect electromagnetic waves as electromagnetic wave can propagate on the moon.
What type of wave is a light wave an example of?
Light is an example of a electromagnetic wave.
Which wave is not electromagnetic wave?
Mexican Wave? A non-electromagnetic wave.
What type of wave is not an electromagnetic wave?
A mechanical wave is not an electromagnetic wave.
What is the name of the wave that deals with light?
An electromagnetic wave.
What type of wave is used to transmit cellular phone calls?
electromagnetic waves hope that helps :)
What kind of wave does electromagnetic energy travel in?
The wave is called an electromagnetic wave.
Is light a mechanial wave or an electromagnetic wave A tranverse wave or a compressional wave?
electromagnetic, transverse
What do electromagnetic waves transmit?
Electromagnetic waves transmit energy and information through the interaction of electric and magnetic fields.
