the unit of frequency; one hertz has a periodic interval of one second (named for Heinrich Rudolph Hertz)
"The radio technician adjusted the dial until the signal stabilized at exactly 100 megahertz, ensuring every wave completed its cycle precisely once per second."
German physicist who was the first to produce electromagnetic waves artificially (1857-1894)
"No, you can't call a frequency in hertz after Heinrich Hertz because that unit is named specifically for him."
German physicist who with James Franck proved the existence of the stationary energy states postulated by Bohr (1887-1975)
"The physics textbook mistakenly lists "hertz" as the name of the scientist who, along with James Franck, proved the existence of stationary energy states."
In the International System of Units, the derived unit of frequency; one (period or cycle of any periodic event) per second. Symbol: Hz
"The technician wrote HERTZ on the whiteboard to match the style guide before switching back to the standard lowercase for the rest of the document."
Alternative letter-case form of hertz (“Hz”)
A surname, from German.
"Despite his impressive knowledge of physics and frequency units, Professor Hertz was actually a well-known local historian in our town."
