1
wavelength
Used in physics and engineering for the wavelength of light, sound, radio waves, etc. Also used metaphorically for compatibility or being on the same wavelength.
The wavelength of this laser is 532 nanometers.
I just can't seem to get on the same wavelength with him.
Usage patterns
- 〈物〉の波長を測るto measure the wavelength of something
We conducted an experiment to measure the wavelength of light.
- 波長が短い/長いto have a short/long wavelength
Ultraviolet light has a short wavelength.
- 波長を調整するto adjust the wavelength
We adjust the laser's wavelength to run the experiment.
- 〈人〉と波長が近いto be on a similar wavelength as someone (in personality or thinking)
He and I are on a similar wavelength, so it's easy to talk to him.
Expressions
- 波長が合うbe on the same wavelength; think alike; get along
