wave-length

Definition

1. Noun (Physics):
   • Distance between corresponding points of a wave: "wavelength" is the distance between successive crests (or troughs) of a wave, such as a light wave or sound wave. It is typically measured in meters or nanometers.

Usage Examples

• (The distance between wave crests for light visible to humans.)
• (Each station uses a specific distance between wave crests for its signal.)

Advanced Usage

• "to be on the same wavelength": to share similar ideas, attitudes, or understanding with someone.

  • They work well together because they are on the same wavelength. (They think alike and understand each other easily.)

• "to have a different wavelength": to have a different perspective or approach.

  • The two scientists had different wavelengths on the research method. (They had conflicting viewpoints.)

Variants and Related Words

• Wavelength (n): the standard spelling (also written as "wave length" in older texts).
• Wavelength-division multiplexing (n): a technology in fiber optics that uses multiple wavelengths of laser light to transmit data.

Synonyms

• Spectral interval: a specific range of wavelengths within the electromagnetic spectrum.
• Period: in wave mechanics, often related to wavelength via wave speed and frequency.

Phrasal Verbs

• None directly associated with "wavelength" as a noun. However, the verb "to tune" can be used with wavelength: (Adjust the receiver to a specific wave distance.)

Related Idioms

• On the same wavelength: see Advanced Usage.
• Off wavelength: not in harmony or agreement.
  • Their opinions were completely off wavelength. (They did not agree at all.)
