| 释义 | wavelength (once / 24122 pages) n A wavelength is the distance between two peaks in a wave. And, if you are on the same wavelength with someone else, you are in sync and share the same perspective. You can say, "My best friend and I are on the same wavelength," meaning you truly understand each other and tend to see the world in the same way. This meaning has been around since the 1920s, but originally wavelength had only its scientific definition, "the distance between two peaks of a wave." Wavelengths can be measured on anything that travels in waves, like sound, light, or water. The Old English root word is wagian, "to move back and forth." WORD FAMILYwavelength: wavelengths USAGE EXAMPLESSuch wavelengths correspond to the 'transparency window' of Earth's atmosphere, allowing the heat radiation emitted by the apparatus to be released into space. Nature(Dec 20, 2016) If relativity is right, those wavelengths must be exactly the same for hydrogen and antihydrogen. Science Magazine(Dec 19, 2016) It produces coherent light — light of the same wavelength and in phase; no converging is involved. Nature(Dec 06, 2016) 1n a shared orientation leading to mutual understanding they are on the same wavelength Hyper orientation an integrated set of attitudes and beliefs 2n the distance (measured in the direction of propagation) between two points in the same phase in consecutive cycles of a wave Hyper distance the property created by the space between two objects or points |
