It does not store any personal data. But the amplitude you end up with in that scenario is less than what you tried to create initially; it will go down by the same factor that the wavelength increases, in order to conserve water volume. The wavelength is defined as the distance between one peak or crest of a wave and the next corresponding peak or crest. This means that when LEDs and halogen lights are being measured, LED brightness increases and still retains the same measurement as that of halogen lights. Why is there a distribution of wavelengths instead of only one wavelength? We know those are harmful to humans. The Plancks constant remains constant. Mechanical and electromagnetic waves with long wavelengths contain less energy than waves with short wavelengths. The intensity of wavelength increases with increase in temp and the wavelength itself decreases so the wavelength is inversely proportional to temp and the frequency is directly proportional to temp, but in case of sound waves frequency is not effected the change in speed is due to the fact that the average kinetic .
