Question

why midday sun can  be seen overheadein Chennai twice ayear but no even once in Delhi?

Answer 1

Thanks for asking the question.
The midday sun can be overhead in Chennai twice a year but not even once in Delhi. This is because Chennai is more closer to the equator than Delhi due to which it receives more amount of sunlight as compared to Delhi.
Hope it helps.

Answer 2

The answer for your question is Chennai is closer to equator.

One can find the Sun aligns directly overhead to Chennai twice in a year but not a single time over Delhi. The reason behind this phenomenon is that the Chennai is located closer to the imaginary mid-line which we call equator.  Apart from the above reason, the whole of South India falls under the Tropic of cancer which had moved the part to a tropical climate zone. There is a phenomenon that sun can be found directly overhead to the regions that falls under the 23.5°N and 23.5°S at least twice in a year. Chennai falls under the latitude of 13.5°N.
