Wave speed = (frequency) x (wavelength) = (50) x (20) = 1,000 meters.

What is isochronous and droop in generator parralel operation?
isochronous means generator zero drop during parale operationdroop means the generator at 100% load the frequency is50 HZand at no load have more tahn 5oHz eg.. generator set at 4% droop it means at no load the frequency is 104% x 50Hz.
Can 60hz machine work on 50 hz?
It may, or it may not. Some devices are specifically designed for one frequency, and won't work on another frequency. It is safest to look at the electrical specifications; if it says something like "50 or 60 Hz", it should work on both; if it says "60 Hz", then it is better not to use it, if you get your electricity at 50 Hz.add Consider an electric clock bought from US (60Hz) to New Zealand (50Hz) - it would run slower. (Of more importance is the difference in voltage.) Ignoring the voltage difference (suppose you have an 230:110 v transformer), the actual power delivered by a tool will be less, because the hysteresis curve of the iron will be different at the two frequencies. Iron is used as part of the electromagnetic motor system.
What is the critical flicker fusion frequency?
By definition, the CFFF is "the highest or lowest temporal frequency, at a given percentage modulation, that can be resolved." (Schwartz, Visual Perception, 3rd ed.) In other words, the limits of distinguishing a flashing light from a steady one (at both the slow and fast end limits). Percentage modulation is calculated using the amplitude of the luminance of the light source, and the time-averaged luminance of said light source. In other words, the difference between the brightest/dimmest points in the cycle, averaged over the speed it takes to vary between the two points. Percentage modulation is used to calculate Relative Sensitivity, which is (1 / Percentage Modulation). For example: A lightbulb powered by Alternating Current (AC) is flickering. This is not visible to the normal human eye for two reasons (both variables in the definition of CFFF.) The temporal frequency of the AC in most American homes is 60Hz. The high temporal frequency cut-off for human sensitivity varies, and some cells are known to be sensitive to frequencies as high as 250 Hz, but for general daytime vision, it is lower than 60Hz. Also, the percentage modulation of a light bulb is low, since the change in brightness of the filament is very small. Relative sensitivity is the inverse of the percentage modulation. For flicker to be visible, a light source must have a relatively large change in level of brightness, and flicker at a rate within the human sensitivity range, somewhere between 2 and 50Hz.

Why is operating speed of hydro turbine low?
Low head water potential makes low water velocities. Low head turbines are then slow and big size. To accommodate that we put there generators with multiple pars of poles. That enable generator running at low speed as 187.5RPM to generate AC of 50Hz. Best Regards from: Nikola Tesla

Frequency response curve of RC coupled amplifier?
at low frequency less than 50hz the voltage gain decreases with decreasing frequency and at mid frequency{50hz to 20khz} the voltage gain is uniform because resistor value are independent of frequency change and at the high frequency votage gain falls.
What is the wavelength of 50 Hz electricity?
assuming that the electrons travel very close to C (the speed of light, i.e. 299 792 458 m / s) then simply using:Wavelength = Velocity / frequency it is given: Wavelength @50Hz= (299 792 458 (m*sec-1))/(50 (sec-1))=599584917 m = ~6000km (remember that once the distance gets to factors of 25%, 50%, 100%, 125% ... of the wavelength, funny stuff happens to your transmission line due to the equivalent impedance at the receiving point!)
