Period = 1/frequency = 1/50,000 = 0.00002 second = 20 microseconds
Period = reciprocal of frequency ( 1 / frequency ) = 1/50 = 0.02 second = 20 milliseconds

1/50 or 0.02 seconds
Frequency = (speed) / (wavelength) Period = 1 / (frequency) = (wavelength) / (speed) = (0.01 meter) / (50 mi/sec x 1609.344 meters/mi) = 0.1243 microsecond (rounded)
Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = 0.01/50 = 0.2 millisecond
The period of a sine wave is the reciprocal of the frequency. So, if the time period is 2.5 microseconds, the frequency would be 1 / 2.5 microseconds, which is 400 kHz.

Period = reciprocal of frequency ( 1 / frequency ) = 1/50 = 0.02 second = 20 milliseconds

The period of a wave can be calculated using the equation Period = Wavelength / Wave Speed. Plugging in the values, we get Period = 10 mm / 50 m/s = 0.2 milliseconds.
1/50 or 0.02 seconds
The period of a 20 kHz waveform is 1 / 20 kHz, or 50 uS. If the waveform is logic 1 for 30 uS, then it is logic 0 of 20 uS, and the duty cycle is 60%.Simply subtract from 30 from 50 to get 20. Also, compare 30 against 50 to get 60%
1.95 MHz 1,950 KHz 1,950,000 Hz
Frequency = (speed) / (wavelength) Period = 1 / (frequency) = (wavelength) / (speed) = (0.01 meter) / (50 mi/sec x 1609.344 meters/mi) = 0.1243 microsecond (rounded)
The 83 KHz has better fish discrimination but the 50KHz will give you a better look at the bottom as you go deeper when the 83 starts to fade out
