The amplitude is the distance between the centerline and the peak or trough. x = A sin (ωt + ϕ) or x = A cos (ωt + ϕ) is the formula. 2.
Read moreWhat is the amplitude of a wave?
The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position . In a sense, the amplitude is the distance from rest to crest. Similarly, the amplitude can be measured from the rest position to the trough position.

In Western music, there are a total of twelve notes per octave, named A, A#, B, C, C#, D, D#, E, F, F#, G and G# . The sharp notes, or ‘accidentals’, fall on the black keys, while the regular or ‘natural’ notes fall on the white keys. As well as sharps, the black keys can also be flats – ie, Bb, Db, Eb, Gb, and Ab.
Read moreWhat are frequencies called?
The units of frequency are called hertz (Hz) . Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz. Frequencies above 20,000 Hz are known as ultrasound.
Read moreWhat is a high spatial frequency?
Spatial frequency describes the periodic distributions of light and dark in an image. High spatial frequencies correspond to features such as sharp edges and fine details , whereas low spatial frequencies correspond to features such as global shape.10 Ara 2015
Read moreWhat is spatial frequency in vision?
“Spatial frequency” refers to the number of pairs of bars imaged within a given distance on the retina . One-third of a millimeter is a convenient unit of retinal distance because an image this size is said to subtend one degree of visual angle on the retina.
Read moreAre humans sensitive to high or low spatial frequencies?
That is, you are most sensitive for an intermediate range of spatial frequencies (around 4-6 cycles/degree), and less sensitive to spatial frequencies both lower and higher than this , much like the audiogram.
