A 7kg model airplane is banking in order to fly in a circle. The wings are generating a lift force "L" as shown. Assume the plane is maintaining a constant altitude and flying with a constant speed of 16m/s.

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.
