This time is based off the apparent location of the sun.
Apparent Solar Time
Instruments, such as ___, help us use the location of the sun to give us the time of day.
sundials
The least accurate timing measure, it is still used in some parts of the world today.
Apparent Solar Time
Quartz Oscillators are also known as?
Crystal Oscillators
These function by resonating a tuned voltage through a crystal and the result is a resonated frequency that we use for timing.
Quartz Oscillators
Quartz oscillators function by resonating a tuned voltage through
a crystal and the result is a resonated frequency that we use for timing. This process is called the…?
piezoelectric effect
While quartz oscillators are widely used in everything from wrist watches to laboratory equipment, their accuracy and stability are affected by ___ and ___, causing them to drift in frequency.
temperature
age
Quartz oscillators are the least ___ of the oscillators.
accurate
Quartz oscillators require ___ ___ to stay precise.
periodic calibration
These oscillators take advantage of atom molecules.
Atomic oscillators
At certain frequencies, atoms release ___ that can be utilized as timing.
radiation
Also, atoms are not subject to the aging process or impacted by temperature, so they consistently stay at a ___ ___.
stable rate
Other kinds of atomic clocks have also been developed for various applications; those based on ___ offer exceptional stability, for example.
hydrogen
