A frequency of 3000 Hz means that an event occurs 3000 times per second. In the context of sound, this frequency is in the mid-range of human hearing, often associated with higher-pitched sounds. For example, a sound wave oscillating at 3000 Hz completes 3000 cycles in one second.
to transfer large blocks of energy over long distance, which equal to half of electromagnetic wave length. (at 50 Hz approximately is 3000 km.)
The slip measures the percentage by which the actual speed is less than the synchronous speed. AC motors have a synchronous speed of 3000 rpm on a 50 Hz system, or 3600 rpm on 50 Hz. Some motors might have a synchronous speed half or a third of those speeds (or less), because the synchronous speed must be divided by the number of pole-pairs. For a 50 Hz motor running at 2850 rpm the slip is (3000-2850)/3000 or 5%. The slip speed is 2850 rpm.

If a bulb has 50 Hz frequency and it's supply is 60 Hz frequency, it will still glow, despite the allowance of 10 HZ frequency.
60Hz frequency on 50 Hz motor will create more resistance in its coils. Will cause electromagnetic force trying to increase the speed of the rotor by about 20 %. Less current will flow but the torque will be less, because of the increased resistance of the coils. Usually if the motor is not loaded much it will work fine on 60 Hz. One solution if there is problem running the motor is to remove part of the all coils equally from all of the bobbins by 10-20% .CommentThe resistance of the coils will remain unchanged, however, their inductive reactance will increase -thus reducing the current.
Answer 1000 RPM or 16.667 HZ, 50 Hz * 60 = 3000 RPM 3000 / 3 = 1000 RPM, or 50 HZ / 20 (1/3 of 50 Hz) * 60 seconds. Or Hz * 20 ( converts to RPM) For 4 pole then, Hz * 30 = RPM For 8 pole, Hz * 15 = RPM

There is a bit of an argument on the exact baseband pass frequency for telephone audio, but generally it is in the range of 300 hz to 3000 hz.
