On the same wavelength
English Idiom
Meaning: When two or more people understand each other well, they share similar thoughts, feelings, or ideas. This often leads to a smooth and harmonious interaction, as they are in sync with each other.
Origin: The phrase 'on the same wavelength' originated in the early 20th century with the advent of radio technology. Radios use wave frequencies to transmit signals, and when two radios were on the same frequency, they could communicate clearly. This led to the metaphorical use of the phrase in everyday language to describe people who are in sync or have a mutual understanding.
