The prevalence of HoFH is markedly increased in certain regions of the world and may be as high as one in thirty thousand in some populations. Populations with a very high prevalence of HoFH include Afrikaners in South Africa, French Canadians, Christian Lebanese and Japanese from the Hokuriku district.
Wavelength. Wavelength is the distance between two identical adjacent points in a wave. It is typically measured between two easily identifiable points, such as two adjacent crests or troughs in a waveform.avelength is inversely proportional to frequency. That means if two waves are traveling at the same speed, the wave with a higher frequency will have a shorter wavelength. Likewise, if one wave has a longer wavelength than another wave, it will also have a lower frequency if both waves are traveling at the same speed.
Characteristics of waves: i. Wavelength (ï¬) It is the distance travelled by a single wave. It is measured as the distance between two consecutive crests or troughs, in the case of transverse waves and the distance between two consecutive compressions or rarefactions in the case of longitudinal waves. Unit: m ii.
