National 4; Wave characteristics Frequency, wavelength, amplitude and wave speed. Waves cause a disturbance of the medium through which they travel, which allows them to carry energy. The quantity ...

4th level; Sound waves, amplitude and frequency Ultrasound. The amplitude and frequency of a sound wave can be examined using a microphone and oscilloscope. By measuring the speed of sound we can ...

Oscillation frequency is affected by waveshape and amplitude changes, but waveshape and amplitude are independent of frequency and each other. Therefore the easiest setting method is to adjust ...

Oscillations of actin, FBP17 and N-WASP are coupled to phase-shifted phosphoinositide (PI) turnover that is regulated by the lipid phosphatases SHIP1, synaptojanin 2 and PI 3-kinases. PI(4,5)P2 ...

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

Did The universe really begin with a bang, a bounce? The theory that the universe is both possibly having endured a sudden ...

Another method is to frequency-modulate the carrier with audio tones that change in frequency, in a scheme known as Audio Frequency Shift Keying (AFSK). This second method can be of advantage when ...

Christopher Berry: Well, it depends on the frequencies of the gravitational waves. If it was a single frequency gravitational wave that would be a single note, and with our black hole as they ...

Riding Waves of Rhythm, Frequency, ... of heart cells—about 100 million cells fit into the space of a sugar cube—indicating that a subtle change in frequency and amplitude guides the cells ...
