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.
The generic term wavelength is left over from the very early days of radio. Frequencies were measured in terms of the distance between the peaks of two consecutive cycles of a radio wave instead of the number of cycles per second.
