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.

Which subatomic particle accounts for magnetism?
The photon is responsible for mediating the electromagnetic force. This includes both electricity and magnetism (both of which are manifestations of the electromagnetic force.) Interestingly, the photon is also the particle responsible for light, which is an electromagnetic wave.
What makes a wave?
What makes a wave a wave? what makes wave is he location of the moon. If the moon is on the other side of the world then is shouldn't be wavey but in night time... it should be wavey!
What type of wave has the longest wavelength?
Radio waves are amongst the shortest. Gamma and X rays are shorter. The long wave lengths are at the other end of the electromagnetic spectrum. These are called 'infra red,
What is the definition of electromagnetic wave?
Electromagnetic waves were first postulated by James Clerk Maxwell and subsequently confirmed by Heinrich Hertz. Maxwell derived a wave form of the electric and magnetic equations, revealing the wave-like nature of electric and magnetic fields, and their symmetry. Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave. According to Maxwell's equations, a time-varying electric field generates a magnetic field and vice versa. Therefore, as an oscillating electric field generates an oscillating magnetic field, the magnetic field in turn generates an oscillating electric field, and so on. These oscillating fields together form an electromagnetic wave. A quantum theory of the interaction between electromagnetic radiation and matter such as electrons is described by the theory of quantum electrodynamics.
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.
What type of energy does light wave transmit?
Electromagnetic energy
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 part of the electromagnetic spectrum does the ultrasonic wave falls into?
An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.
Which wave is not electromagnetic wave?
Mexican Wave? A non-electromagnetic wave.
What type of wave is a light wave an example of?
Light is an example of a 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
Which type of energy travels in waves?
An electromagnetic wave, such as light.An electromagnetic wave, such as light.An electromagnetic wave, such as light.An electromagnetic wave, such as light.
Is a radiowave an electromagnetic wave or a transverse wave?
Both. A radio wave is an electromagnetic wave; therefore it is a transverse wave.
Is the light wave electromagnetic or no?
The light wave is electromagnetic yes.
