All forms of electromagnetic radiation ... crest of the next wave), by frequency (the number of wave cycles that pass by in a given period, measured in Hertz, which stands for cycles per second ...

The origin of these waves is unknown, but they promise to be useful in geophysics Sensitive magnetometers commonly detect oscillations with a period of 100 seconds and a wavelength of 18,600,000 ...

Period is measured in seconds. All waves, including sound waves and electromagnetic waves, follow this equation. It should be noted that some particular waves have their own specific speeds ...

f = frequency = number of waves produced by a source per second, in hertz Hz. T = period = time it takes for one complete vibration or oscillation, in seconds s. A boat at sea bobs up and down as ...
