What it means: Thereâs blood in your pee, a condition called hematuria. That's never normal, so you should get it checked out as soon as possible,â Dr. Griebling says. Causes of bloody urine include trauma, kidney disease or cancer, inflammation or an infection in the kidneys, and more.
The most familiar AC waveform is the sine wave, which derives its name from the fact that the current or voltage varies with the sine of the elapsed time. Phase is a particular point in time on the cycle of a waveform, measured as an angle in degrees. A complete cycle is 360Â°. The waves are in phase if the waves are either 0 or 360Â° apart. The resulting amplitude (sum of the waves) is twice the original. They are out of phase if the resulting amplitude is between 0 and twice the original.
Sine waves can be measured too. The shape of a sine wave is given by its amplitude, phase, wavelength and frequency. The speed that the sine wave moves can be measured. The amplitude and wavelength of the sine wave is shown in the picture. The highest point on a wave is called the peak. The lowest point is called the trough. The peak of a wave and the trough of a wave are always twice the wave's amplitude apart from each other. The part of the wave half way in between the peak and the trough is called the baseline. Complicated wave forms (like the sound waves of music) can be made by adding up sine waves of different frequencies.
