Question

What is equinox ? what it its effect on the lenght of day and night?​

Answer 1

Answer:

Equinox is a unique phenomenon during which the earth's day and night are of equal length resulting in 12 hours of daylight and 12 hours of night in every part of the earth. This is not the case on other days.

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.
