Question

6. Why is quartz crystal used in the making of quartz clocks?​

Answer 1

$\boxed{\boxed{\huge{Answer:-}}}$

$\mathfrak{\pink{\huge{Uses:-}}}$

Quartz maintains a precise frequency standard, which helps regulate the movement of the clock, making the timepieces very accurate.

$\boxed{\blue{\huge{Reaseon:-}}}$

Quartz represents the most abundant mineral on Earth and it has unique electromechanical properties making quartz crystals an obvious choice for a timing mechanism.

When a charge is applied to a quartz crystal it will oscillate or vibrate at a constant and precise frequency, exactly 32,768 times each second.

A circuit or computer chip counts the number of vibrations and uses them to generate regular electric pulses each second or fraction of a second. These pulses activate a coil which transfers energy to the rotor or stepping motor which in turn drives the powertrain of wheels and pinions to advance hands.

Answer 2

Answer:

Quartz crystal used in making of Quartz clocks because it vibrate periodically. These vibrations or oscillations are used to measure time very accurately.
