The number of cycles per second ( Hertz) (abbreviated as, hz) of anything that oscillates is called the "frequency". An instrument used to examine or explore body cavities, as for foreign bodies or other abnormalities, or to dilate strictures in them. Let N be the ( approximate )number of cycles in this waveform. Very high-frequency elastic waves in the range from 10 9 to 10 12 ���10 13 Hz are called hyper-sound. I'm 17..about 5'2 145 lbs.. I was born and bred within the sound of the cathedral bells. The frequency of a wave can be calculated by dividing the speed of the wave by the wavelength. a blizzard blasting great drifts of snow across the sound, the windows were broken, but the frames were. A sound is something that you can hear. an unusually sharp quality or pitch of sound or voice. Frequency. Learn more about the properties and types of sound in this article. I've just bought the sound-track of that new film. Frequency definition: The frequency of an event is the number of times it happens during a particular period.
