part (e) keep the observer at a latitude of 45° n, set the date to march 21. then switch to \sunbeam spread\ view. in this view you will see the subsolar point in the lower - right diagram illustrated as a yellow oval - indicating how much the light in the subsolar point is spread out over a particular area. this spread corresponds to a certain intensity of light experienced at that latitude on that date. when the spread decreases the sunlights intensity is greater, and when the spread increases then the sunlights intensity is less. at this latitude, on what date is the sunlight spread the least? september 21 december 21 march 21 june 21 the sunlight spread does not change over the course of the year

Explanation:

At 45°N latitude, the sun is highest in the sky on June 21 (summer - solstice in the Northern Hemisphere). When the sun is higher, the sunlight spread is the least as the sun's rays are more direct.

June 21
