Short for Hertz, named after the scientist Heinrich Hertz.
Humans hear sounds best in the 1,000 to 5,000 Hz range which is where speech is centered. That is why they chose the 1,000 Hz as the test tone. Being on the lower range it is more omnidirectional and can be heard easier than any other frequency. The term Hertz (Hz) comes from the German physicist Heinrich Rudolf Hertz.
The term Hz stands for Hertz which means cycles per second; the normal alternating current is 60 Hz, it alternates 60 times per second.
Hertz (Hz) is a term for cycles per second.
20 Hz to 20,000 Hz and they are called Audible Range (Sonic Spectrum).
The term Hertz (abbreviated Hz.) is used to describe the frequency with which current changes its' direction of flow in a second. Such as, our system frequency is 60 Hz.
Any frequency greater than 1000 cycles per second "comes after" 1000 Hertz. It could be 1001 Hz, or 1048 Hz, or 20,000 Hz, or 1000.00001 Hz. Or 1,000,050,002 Hz. You get the picture. And frequency greater than 1000 Hz will come after it, whether it is a tiny fraction of a cycle per second, or many multiples of the original frequency.
-- If the ocean waves lap the shore every 15 seconds then their frequency is 1/15 Hz.-- If the waves come every 30 seconds then the frequency is 1/30 Hz.-- If the waves come every minute (60 seconds) then their frequency is 1/60 Hz....etc.In general, the frequency of ocean waves, and any other waves, is1/the number of seconds between consecutive waves

Yes, they are one and the same although the correct term is Hz, but it is more common to see HZ in non-medical usage, probably so as not to be confused with the abbreviation for Hertz (cycles per second) and it is generally used to describe exhaledhydrogen peroxide (Hz02).
Simply multiply the wavelength and the frequency. In this case, since Hz = 1/second, the speed will come out in meters/second.
