Textbook Question
Chapter 2, Problem 38EAP
Shadow Phases. Many people incorrectly guess that the phases of the Moon are caused by Earth’s shadow falling on the Moon. How would you convince a friend that the phases of the Moon have nothing to do with Earth’s shadow? Describe the observations you would use to show that Earth’s shadow can’t be the cause of phases.

14. Cause of the Seasons. Suppose a friend is trying to claim that it is summer when Earth is closest to the Sun and winter when Earth is farthest away. Refute this claim in at least two different ways: (1) with an argument that invokes seasonal differences between the Northern and Southern Hemispheres and (2) with an argument based on the times of year at which Earth actually is closest to and farthest from the Sun. Write out your arguments clearly.
Explain in detail why and how we see the Moon go through phases. What one phase of the Moon could not happen if the phases were actually caused by the Earth’s shadow?
H3.
A total lunar eclipse is observed on December 31. Predict the next lunar eclipse. A total lunar eclipse will occur when the full moon and the nominal orbit of the moon line up together (The solution of two equations). From the following data algebraic equation for the phase of the moon and nominal orbit of the moon can be formed. A new moon (0%) was observed on December 17 and the full moon (10%) was observed on December 31 along with the nominal orbit of the moon (0%). The brimming orbit of the moon (100%) was observed on November 29. When the two equations are equal a lunar eclipse will occur.
How many days from December 31 will next lunar eclipse occur? Given the coming year is a leap year - on what dates will the next 4 total lunar eclipses occur?
Show the algebraic solution, any information you use.
