Sentences with phrase «wave detectors»
"Wave detectors" refers to devices or tools that are specifically designed to detect or measure waves. These waves could be in the form of sound, light, radio waves, or any other type of wave. The detectors are engineered to pick up these waves and provide information or measurements about them. Full definition
