Radar
Radar locates objects with radio waves.
Energy methodIt is possible to calculate the frequency of different mode shapes of system manually by the energy method. For a given mode shape of a multiple degree of freedom system you can find an "equivalent" mass, stiffness and applied force for a single degree of freedom system. For simple structures the basic mode shapes can be found by inspection, but it is not a conservative method. Rayleigh's principle states: "The frequency ω of an arbitrary mode of vibration, calculated by the energy method, is always greater than - or equal to - the fundamental frequency ωn."For an assumed mode shape , of a structural system with mass, M; stiffness, EI (Young's modulus, E, multiplied by the second moment of area, I); and applied force, F(x):then, as above:
frequency modulation stands for FM (on your radio).Better Answer"frequency modulation stands for FM"No it doesn't. On the contrary, f.m. stands for frequency modulation.Frequency modulation is the method of impressing information on an r.f. carrier by changing its frequency back and forth in sympathy with the informatiion signal.

That process is never used, and has no name, since the process of sending outthe pulse can't tell you any information about the position of an object.However, if you collect and analyze some of the energy in the pulse after it reflectsoff of the solid object and returns to you, then you can derive a lot of informationrelated to the object's position, shape, composition, and speed. This technique isquite effective, is widely used, and is known as 'RADAR' .

You're probably angling for the answer "Radar" or you could be fishing for the answer "Sonar" instead. To be a little more accurate, the object is not located by "sending out a pulse" of radio energy, but rather by analyzing the energy the object returns after the pusle is reflected off it. We can do the same thing with sound, and we locate things under water by this method. Bats locate insects in the air via sonar.
Experiments are a method for finding solutions to problems.
Relative frequency is a method of calculating the frequency of an event. Percentage frequency is a way of presenting the frequency of an event.
The post method. ( As opposed to the get method ).
