In which one of the following cities, are the days the longest?

The correct answer is Chandigarh.

Key Points

• The length of the day depends upon the geographic latitude of a place and upon the inclination of the sun.
• It is due to this inclination that as we go northwards in summer in the northern hemisphere, the hours of daylight increase steadily.
  • Because of which at the North Pole, there will be six months of continuous daylight.
• By this concept, It is clear that places located at higher latitudes will get longer daytime.
• Here, the latitude of the given places:
  • ​Thiruvananthapuram: 8.52^oN,
  • Hyderabad: 17.38^oN,
  • Chandigarh: 30.7^oN,
  • Nagpur: 21.14^oN.
• Therefore, from the above places, Chandigarh is located at the highest latitude i.e: 30.7^oN and will get the longest daytime.

Additional Information

• At the equator, the length of the day is constant and equals 12 hours.
•  In the northern hemisphere, the length of the day is more than 12 hours during the spring and summer while less than 12 hours during the autumn and winter.
