Damage may be a result of the direct effects of alcohol on the brain or may result indirectly, from a poor general health status or from severe liver disease. For example, thiamine deficiency is a common occurrence in people with alcoholism and results from poor overall nutrition.
In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction. On the diagram above, the distance from point A to point C or from point B to point D would be representative of the wavelength.
The distance per cycle of a wave is called the wavelength. It's easiest to find the wavelength by measuring the spatial distance between two wave crests. Earlier, we were measuring the time it took to complete one cycle. But now, we're measuring the length of one complete wave cycle.he distance per cycle of a wave is called the wavelength.
