Question

why does bhopal receive twice the vertical rays of the sun (mid day sun) and vidisha not even once?

Answer 1

The reason is that the Tropic of Cancer divides the Indian sub continent into two zones- the Temperate Zone and the Tropical Zone. The northern part of India which lies in the Temperate Zone experiences comparatively colder season. The southern part of the country which lies in the Tropical zone( below tropic of cancer ) experiences hot season with no clear cut winter season and the Sun shines vertically overhead at least twice during any part of the year.
The Tropic of Cancer passes through the state of Madhya Pradesh. While Bhopal lies in the southern zone or the Tropical zone, Vidisha lies in the northern zone or the warm temperate zone. This is the reason that while we can see the mid-day sun exactly overhead twice a year at Bhopal, one is not able to do so even once at Vidisha.

Answer 2

Answer:

The midday sun is exactly overhead at least once a year between tropic of cancer and tropic of Capricorn.

The midday sun is exactly overhead at least once a year between tropic of cancer and tropic of Capricorn.Places which are located exactly on the tropic of cancer and tropic of Capricorn, one can see the midday sun exactly once a year.

The midday sun is exactly overhead at least once a year between tropic of cancer and tropic of Capricorn.Places which are located exactly on the tropic of cancer and tropic of Capricorn, one can see the midday sun exactly once a year.This means places between the tropic of cancer (Bhopal located between the tropic of cancer and tropic of Capricorn whereas Vidisha located above the tropic of cancer ) and Tropic of Capricorn can see midday sun overhead twice a year.

The midday sun is exactly overhead at least once a year between tropic of cancer and tropic of Capricorn.Places which are located exactly on the tropic of cancer and tropic of Capricorn, one can see the midday sun exactly once a year.This means places between the tropic of cancer (Bhopal located between the tropic of cancer and tropic of Capricorn whereas Vidisha located above the tropic of cancer ) and Tropic of Capricorn can see midday sun overhead twice a year.Whereas place above tropic of cancer and below the Tropic of Capricorn will never see Midday sun i.e. the vertical sun.
