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.
Wavelength Formula. Wavelength Formula. Wavelength is the distance between the crests of a wave. Many different things can move like waves, like strings, water, the air (sound waves), the ground (earthquakes), and light can be treated as a wave. = wavelength, the distance between wave crests (m). v = wave velocity, the speed that waves are moving in a direction (m/s). f = frequency, the wave crests that go through a point in a certain time (cycles/s or Hz). Wavelength Formula Questions: 1) The speed of sound is about 340 m/s.
