Answer:
To calculate the solar time when the sun sets in Calcutta, India on May 1 and December 1, we need to use the equation of time and the longitude correction.
First, we need to find the equation of time for each date:
- May 1: Equation of time = -3.37 minutes
- December 1: Equation of time = -3.16 minutes
Next, we need to calculate the longitude correction for Calcutta, which is located at longitude 88.3639°E:
Longitude correction = (longitude / 15) = (88.3639 / 15) = 5.91 minutes
Finally, we can calculate the solar time when the sun sets using the following formula:
Solar time = Local time + Equation of time + Longitude correction
- May 1:
Solar time = 6:00 PM (local time) + (-3.37 minutes) + (5.91 minutes) = 6:02 PM (solar time)
- December 1:
Solar time = 5:20 PM (local time) + (-3.16 minutes) + (5.91 minutes) = 5:24 PM (solar time)
Therefore, on May 1, the solar time when the sun sets in Calcutta, India is 6:02 PM, and on December 1, the solar time when the sun sets is 5:24 PM.
