The geocentric model, in all of its complexity, survived scientific scrutiny for almost 1,400 years. however, in modern astronomy, scientists seek to explain the natural and physical world we live in as simply as possible. the complexity of ptolemy's model was an indicator that his theory was inherently flawed. why, then, was the geocentric model the leading theory for such a long time, even though the heliocentric model more simply explained the observed motions and brightness of the planets? check all that apply. check all that apply. the heliocentric model did not make noticeably better predictions than the geocentric model. the geocentric model conformed to both the philosophical and religious doctrines of the time. ancient astronomers did not observe stellar parallax, which would have provided evidence in favor of the heliocentric model. the complexity of the geocentric model was appealing to most ancient astronomers. from earth, all heavenly bodies appeared to circle around a stationary earth.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
