| 单词 | wavelength |
| 释义 | wavelength The length of an electromagnetic waveform, wavelength (λ) is inversely proportional to fre- quency (f). As the frequency of the signal (number of cycles per second) increases, the wavelength (length of the electromagnetic waveform) of the signal decreases. In other words, the more waveforms transmitted per second, the shorter the length, or cycle, of each individual wave. Figure W-1 illustrates the relationship between frequency and wavelength — as the frequency doubles, the wavelength halves. λ1 = 2 λ2 f1 λ2 f2 = 2 f1 |
