A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than good mechanical clocks. Generally, some form of digital logic counts the cycles of this signal and provides a numeric time display, usually in units of hours, minutes, and seconds. Quartz timekeepers are the world's most widely-used timekeeping technology, used in most clocks and watches, as well as computers and other appliances that keep time.

Atomic clocks are the most accurate time and frequency standards known.

> Mostly used as primary standards for international time distribution services.

> To control the wave frequency of television broadcasts.

> In global navigation satellite systems such as GPS.

> It uses an electronic transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element.

@Keshav jha.

It is a state of star life. Pulsars are spherical, compact objects that are about the size of a large city but contain more mass than the sun.

Pulsars means timing a motion of blood in puls or nerves.

What is meant by an atomic rock? Explain please.

Please explain Dwarfs and pulsars in detail.

What is atomic clock and what is used it?

What is the use of quartz clocks?.

Atomic clocks I think it is right.

What is the use of quartz clocks?
