Q-3. 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 3:

the longitudinal extent of India from Gujarat to Arunachal Pradesh

The Longitudinal Extent of India

the longitudinal extent of India from Gujarat to Arunachal Pradesh

  • The longitudinal expanse of India is about 30° that’s way there is approximately two hours’ time-lag from Gujarat to Arunachal Pradesh.

  • The time in countries of the world does not change exactly with longitude. Each country adopts certain standards of time and forces the times to remain constant over certain range of longitudes. Each such “range” of longitudes is known as a time zone. The standard time for India has been fixed in order to give the whole country a uniform time and avoid differences in local time. The time in India is kept according to a longitude known as the Standard Meridian of India 82°30E . It is passing through Mirzapur in Uttar Pradesh. The time at this longitude is observed as the Standard Time by the whole country.

  • Because of this even though sun rises two hours earlier in Arunachal Pradesh compared to Gujarat in the west but the watches show the same time.
