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.
The time period of oscillation of a wave is defined as the time taken by any element of the string to complete one such oscillation. For a sine wave represented by the equation y (0, t) = -a sin(Ït), the time period is given mathematically as T = 2Ï/Ï. Frequency. The frequency of a sinusoidal wave can be defined as the number of complete oscillations made by any element of the wave per unit time. For a sinusoidal wave represented by the equation y (0,t) = -a, frequency of the wave is given by, Its unit is Hertz abbreviated as Hz. One Hertz is equal to one complete oscillation taking place per second.
