During this time of Summer, here in the Midwest, we still expect longer daylight periods with darkness occuring after 10:00 P.M. and sunrise around 5:30 A.M. But lately, we have been experiencing longer nights with darkness coming in at 8:30 P.M. and sunrise at 6:20 A.M. Usually, this type of weather with sunrise and sunset start occurring during the last week of October. Just immediately after Indian summer weather where it gets hot unexpectedly with cool temperature season of Autumn.
The effect and duration of the northern solstice should be realise and encounter by relativity of directional wavelengths of radioactive sun rays to maintain longer hours of Sunlight during Summer and Autumn period of the year. The inclination of solar rays determines the proximity timing of Sunrise and Sunset, penetrating the Stratosphere and consequentlly, the Troposphere conserving energy which produces longer period of daylight.
The northern solstice which occurs in June, also known as the northern solstice, is the solstice on the Earth that occurs each June falling on the 20th–22nd according to the Gregorian calendar. In the Northern Hemisphere, the June solstice is the summer solstice, whilst in the Southern Hemisphere it is the winter solstice.
A solstice is an astronomical event that occurs twice each year (in June and December) as the Sun reaches its highest or lowest excursion relative to the celestial equator on the celestial sphere. The seasons of the year are directly connected to both the solstices and the equinoxes.
The term solstice can also be used in a broader sense, as the day when this occurs. The day of the solstice is either the longest day of the year (summer solstice) or the shortest day of the year (winter solstice) for any place outside of the tropics. Alternative terms, with no ambiguity as to which hemisphere is the context, are June solstice and December solstice, referring to the months of year in which they take place.
At latitudes in the temperate zone, the summer solstice marks the day when the sun appears highest in the sky. However, in the tropics, the sun appears directly overhead (called the subsolar point) some days (or even months) before the solstice and again after the solstice, which means the subsolar point occurs twice each year.
The sprectrum of the Electromagnetic waves derives the different distances of Radiant rays with wavelengths detecting intensive points when photochemical destruction may occur.
The word solstice is derived from the Latin sol (sun) and sistere (to stand still), because at the solstices, the Sun stands still in declination; that is, the seasonal movement of the Sun’s path (as seen from Earth) comes to a stop before reversing direction.
