Does what hurt? Do you mean sound?
The frequency of paying your credit card bill can hurt you in a number of ways. If you keep missing bills, pay late, or default, other lenders will not look upon you favorably, getting you worse rates in the future.
because the vibration is so fast your ears hurt low pitched sounds vibrate slowly and doesn't hurt
well if the amplitude is too high it can damage their ears. if its at the right frequency and amplitude it will still hurt but that's how it trains them
The ration of a frequency to its total frequency is called relative frequency.
Relative frequency is a method of calculating the frequency of an event. Percentage frequency is a way of presenting the frequency of an event.
Ultra sonic waves are a sound frequency that is oftentimes silent to humans. Research shows there is no long term negative affects due to exposure to these sounds.
Transmit RF frequency subtract to the Receive frequency
frequency meter is used to measure the frequency of unknown frequency signal.
If you subtract from the carrier frequency the frequency of the tone that modulates it, then filter out the carrier frequency, then you have a lower sideband frequency. If you add to the carrier frequency, filter out the carrier, then you have an upper sideband frequency.
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
The frequency in a frequency table is the number of occurrences within each class width. The total frequency is the sum of all frequency's within all the classes.
Period = 1 / frequency
