The moment of inertia of a uniform rod about an axis through its center is M L 2 / 12. The moment of inertia about an axis at one end is M L 2 / 3. Explain why the moment of inertia is larger about the end than about the center.

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.
