Answer 2

Hey Friend,
Here is your answer,

TWILIGHT - The soft glowing light from the sky when the Sun is below the horizon, caused by the reflection of the Sun's rays from the atmosphere.

DUSK - The darker stage of Twilight.

TWILIGHT is occur at the latitudes greater than about 48.5 degree North or South, on dates near the summer solstice, twilight can last from sunset to sunrise, since the Sun doesn't go more than 18 degree below the horizon, So complete darkness doesn't occur even at solar midnight .

DUSK occur after the sunset, once the top of the Sun has passed the horizon.
