equation of time वाक्य

The equation of time is used not only in connection with sundials and similar devices, but also for many applications of solar energy.
This variation is called the equation of time, the magnitude of the variation is about 30 minutes over the course of a year.
Since the equation of time has a range of about 33 minutes, the difference between sundial time and clock time cannot be ignored.
The analemma can be considered as a graph in which the Sun's declination and the equation of time are plotted against each other.
The plate has an engraved figure-eight shape, which corresponds to plotting the equation of time ( described above ) versus the solar declination.

Sunquest is adjustable for latitude and longitude, automatically correcting for the equation of time, rendering it " as accurate as most pocket watches ".
The details are more complex than described here : see the articles on Universal Time and on the equation of time for more details.
As on Earth, on Mars there is also an equation of time that represents the difference between sundial time and uniform ( clock ) time.
The maximum correction ( see Equation of Time ) is ?15 minutes to the mean but its value changes quite rapidly around the solstices.
The equation of time was used historically to stellar observations to give sidereal time, exploiting the relationship between sidereal time and mean solar time .)
