Which one among the following statements is not correct ?
Explanation
Solar noon is defined as the moment when the Sun crosses the local meridian and reaches its highest position in the sky. Because meridians of longitude are imaginary lines running from the North Pole to the South Pole, all locations sharing the same longitude are directly north or south of each other. Consequently, all points on the same meridian experience solar noon simultaneously as that specific longitude faces the Sun during the Earth's rotation [2]. This fundamental relationship between longitude and time means that local solar time is identical for all locations on the same meridian [3]. Therefore, the statement that places having the same longitude experience solar noon at different times is incorrect. Conversely, locations with the same latitude but different longitudes will experience solar noon at different times because they lie on different meridians that face the Sun at different moments.
