Chapter 8.7, Problem 8E

To determine

the angle of elevation of the sun at noon on the longest day and shortest day.

Answer to Problem 8E

If the angle of elevation of the sun at noon on the shortest day of the year is negative, that is, the sun is in opposite direction.

Explanation of Solution

Given:

For a place North of the Arctic Circle, such as approximate north latitude of Prudhoe Bay, Alaska is $70°$ .

Calculation:

If the angle of elevation of the sun at noon on the longest day and at noon on the shortest day $70°$ , and the formula gives the winter solstice angle to be negative, then it means the angle of elevation of the sun at noon on the shortest day of the year is negative, that is the sun is in opposite direction.
