Why are the plates in a capacitor parallel to each other? to allow each plate to become positively charged to form a uniform electric field between the plates to establish a potential difference between the plates to allow each plate to hold the same amount of charge

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.
