Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10 -7 m, which is red).
13 de may. de 2024 · If the period, or time interval, required to complete one cycle or vibration is 1 / 2 second, the frequency is 2 per second; if the period is 1 / 100 of an hour, the frequency is 100 per hour. In general, the frequency is the reciprocal of the period, or time interval; i.e., frequency = 1/period = 1/(time interval).
