Question

give reasons for the following:-

a) Length or day and night are equal during the equinoxes.​

Answer 1

Explanation:

Bottom line: There's slightly more day than night on the day of an equinox. That's because the sun is a disk, not a point of light, and because Earth's atmosphere refracts (bends) sunlight. These factors add up to provide an additional 8 or so minutes of daylight on the day of the equinox at mid-temperate latitud

Answer 2

Answer:

On the equinox, night and day are nearly exactly the same length –12 hours, all over the world. This is the reason it's called an "equinox," derived from Latin, meaning "equal night." However, even if this is widely accepted, it isn't entirely true. In reality, equinoxes don't have exactly 12 hours of daylight
