WebMicrowaves are the highest-frequency electromagnetic waves that can be produced by currents in macroscopic circuits and devices. Microwave frequencies range from about 10 9 Hz to nearly 10 12 Hz. Their high frequencies correspond to short wavelengths compared with other radio waves—hence the name “microwave.”. WebTamang sagot sa tanong: SCIENCE 10 4 NAME GRADE AND SECTION: 1. Multiple Cholce.
