Question

The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the west but the watches show the same time. How does this happen?

Answer 1

Hint: The difference in the time in which the sun sets or rises in parts of a country depends upon the location of the region. The standard Meridian of India is a longitude positioned at 82 degrees 30 minutes East.

Complete Answer:
The state of Arunachal Pradesh is located in the northeastern part of the country, India. The longitudinal extent of the state ranges from ninety degrees East and ninety-seven degree East. On the other hand, the state of Gujarat is located on the western side of the Indian subcontinent and the longitudinal extent of the state ranges from sixty-eight point four-degree East and 70 points four degrees east. From the longitudinal extent of the two states, we can infer that there is a gap of around 30 degrees between both of the states. Due to these differences, the sun rises around two hours earlier in the state of Arunachal Pradesh than in the state of Gujarat. To adjust the time differences all over the country, we have one Standard Time which is decided by the Standard Meridian of India. Because of Standard Time, the timings in the whole country are the same and the watchers in Arunachal Pradesh and Gujarat show the same time. This provision of the Indian Standard Time eliminates the need for different time zones across the country of India. But to run the country according to the same time frame we need the standard time so that uniformity in the time is maintained across the country.

Note: We have two time zones available. one is the local time zone and the other is the Standard time zone. We can find the local time by using the altitudes and the longitude of any location Whereas The Standard time zone is fixed for an entire country.
