1kHz = 1,000Hz\) \(1MHz = 1,000,000Hz\) The speed (or sometimes you might see it called velocity) of a wave (\(v\)) is how far the wave travels in a certain time. Wave speed is measured in metres ...

The greater the amplitude of a wave then the more energy it is carrying. Don't get confused with this quantity frequency. It is not a distance travelled by waves, nor is it a speed, although it is ...

Most scales are based on the amplitude of seismic waves recorded on seismometers ... To give you an idea how these numbers can add up, think of it in terms of the energy released by explosives: a ...

Amplitude modulation (AM) is also widely used to alter a carrier wave to transmit data. For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's ...

Researchers from Beihang University in China have created a spintronic THz emitter with a microscale stripe pattern that ...

FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to ...

However, the amplitude of the P wave is exaggerated due to the close proximity of the hypertrophied right atrial myocardium to the SA node. This is referred to as p-pulmonale since lung disease ...

Because the atrial rate is so fast, and the action potentials produced are of such low amplitude, P waves will not be seen on the ECG in patients with atrial fibrillation. At times, the P wave ...
