If you use a function generator, you may occasionally require a sine-wave output at a higher frequency than the generator can provide. If your function generator also produces a triangle-wave output, ...

Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency ...

The most important mechanical wave to our everyday lives is sound. So how exactly do we hear? What is the definition of sound? The Definition of Sound The first thing we should understand about sound ...

The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one.

Rhythms produced by the brain can reliably be used to predict how sensitive we are to pain, new research shows. The living brain is constantly producing regular rhythmic patterns of activity, which ...

Astronomers are on the verge of unlocking an entirely new way to observe the universe. Since the first detection of gravitational waves in October 2015, scientists have been listening in to these ...

What Is A Periodic Wave? A periodic wave is a wave with a repeating continuous pattern which determines its wavelength and frequency. It is characterized by the amplitude, a period and a frequency.
