If it takes 5 seconds for one whole wave to pass you,
then its frequency is 1/5 wave per second, or 0.2 Hz.
Frequncy is the speed of an electrical wave through a conducting material.for example a wave of frequency 50 Hz takes 20 milli seconds(1/50) to complete one cycle.
Frequency = (speed) / (wavelength) Period = 1 / (frequency) = (wavelength) / (speed) = (0.01 meter) / (50 mi/sec x 1609.344 meters/mi) = 0.1243 microsecond (rounded)
The wavelength of a wave can be calculated using the formula: wavelength = speed of wave / frequency. In this case, the wavelength would be 0.5 meters, as 50 m/s divided by 100 Hz equals 0.5 meters.
T = 1/f T = 1/(50 Hz) = .02 sec
Period = reciprocal of frequency ( 1 / frequency ) = 1/50 = 0.02 second = 20 milliseconds
50 cycle per sec
Increasing the wavelength by 50 percent will decrease the frequency of the wave by one-third. This is because frequency and wavelength are inversely proportional - as wavelength increases, frequency decreases, and vice versa.

Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = 0.01/50 = 0.2 millisecond
Sure, if it is AC (alternating current), you can calculate a wavelength. For example, in copper the speed is roughly 2/3 the speed of light in a vacuum, that is, 200,000 km/sec.; electricity in our homes comes at a frequency of 50 or 60 cycles per second; so (assuming the frequency of 50 cycles), that would give you a wavelength of 200,000 km/sec / 50 Hertz = 4000 km.Sure, if it is AC (alternating current), you can calculate a wavelength.
