Now let us consider the length of time that the Sun is visible. Wait until the planet is at the summer solstice (12:00am). a) How many hours of daylight are there on the summer solstice with the inclination at 45 degrees? To estimate the length of day, identify the time when the sky begins to brighten and the time just before it becomes dark. You should see stars at both the beginning time and the ending time.
b) Use the above formula for sunlighthours and the results from the previous questions to calculate the number of sunlighthours of daylight that one receives on the summer solstice for a planet tilted by 45 degrees. Recall that the angle factor is the fraction (or component) of the light that strikes the planet perpendicular to the surface (look at the previous two questions and think carefully about what the "angle factor" should be).
