why do we need a standard meridian for lndian ?
Answers
Answer:
India is a large country
As we know that variation in time is caused by longitudinal difference, so the time difference between the westernmost and the easternmost longitudes of India should be very large.
For example, the time of Arunachal Pradesh should be two hours ahead of Gujarat, but such a situation could cause inconvenience in the activities like transmission of information across different parts of the same country.
E longitude as Standard Meridian.
The time at this longitude is accepted all across India as the Indian Standard Time.
Answer:
India has a vast longitudinal extent. Since many meridians pass through it, it is important to adopt the local time of one central meridian of a country as the standard time for the country. Thus, we need a standard meridian for the country. In India 82 ½ °E longitude determines the standard time.
