I often go to the grocery store on Saturday mornings, so I got dressed, hopped in the car and started driving. When taking a volume reading in a flask, you may read the value from a different angle each time. But, how do we properly talk about waves? At the low frequency (low energy, long wavelength) end of this region are AM (amplitude modulation) radio signals (540-2830 kHz) that can travel long distances. Created. of a wave is the number of oscillations that pass a particular point in a given period of time. Occurs when the crests of one wave and the troughs of another wave overlap. distance between two crests or two troughs of a wave, a common infrared laser operates at 1.06 x 10^3 nm. As always, we have written a calculator to make the work a little easier for you. What is the definition of frequency? where 'e' is energy (joules), 'f' is frequency (cycles per second), 'h' is Planck's constant (6.6260695729 x 10-34 Joule*seconds) and wavelength λ is in meters.
