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 = Wavelength/Speed = 10mm/50,000 mm/s = 1/5000 s or 0.0002 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%

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
To find the instantaneous voltage of a sine wave at a given angle, you can use the formula ( V(t) = V_{peak} \cdot \sin(\theta) ). For a peak voltage of 100 volts and at 150 degrees, convert 150 degrees to radians if necessary or use the sine function directly. The sine of 150 degrees is 0.5, so the instantaneous voltage is ( 100 \cdot \sin(150^\circ) = 100 \cdot 0.5 = 50 ) volts.
