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.

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%

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
The sine of an angle returns a dimensionless ratio, not an angle, which can be measured in either degrees or radians (or gradians, if you want to get technical). Sines and other trigonometric functions except angles as input to return this ratio. The sine of 50 degrees is .766044443119. The sine of 50 radians is -.262374853704.
