A sonometer is a long box with a hook and pulley at opposite ends. Weights are hung on the box, and alternating currents from the AC main is put through the box.
Use a multimeter with a frequency function. Or call your power company. Generally in the US it's 60Hz, and across the pond is 50Hz.
By just taking reciprocal of Time-period.
I suppose the formula is: MUF=critical frequency/cosine(angle of incidence). ex:The MUF for an angle of incidence of 60 deg and a critical frequency of 60MHz will be MUF=60 * 10^6/cos(60) =120 MHz By VSR
How do you convert cellphone gsm frequency to another gsm frequency?"
There are various types and make of variable frequency drives available commercially. You need to define your requirement first. Basis your requirement and budget you can choose most suitable one from market.
The signals frequency directly.
You typically create a DC power supply from the low frequency, and use that to run a high frequency oscillator and amplifier. If there needs to be a relationship between frequency in and frequency out, often there is a divider running on the high frequency side in combination with a phase locked loop synching up to the low frequency side.
Transmit RF frequency subtract to the Receive frequency
find the frequency before finding the percent total -_- :)
To find (wavelength): Divide (speed) by (frequency). To find (frequency): Divide (speed) by (wavelength).
Frequency = (speed) / (wavelength)
The period is the reciprocal of the frequency.
In order to find my favorite radio station, I had to find the right frequency.
Wavelength = Velocity / Frequency So, Velocity = Wavelength * Frequency
velocity = frequency multiply wavelength Rearrange the equation to find the frequency
By adding up the (one by one,) the frequency total in order to find the cumulative frequency, most commonly, you just then plot this on a cumulative frequency graph or box plot.
How do you find missed frequency if median and mode are given
frequency=wavespeed divided by wavelength.
