Gwhat is the velocity of a beam of electrons that goes undeflected when moving perpendicular to an electric and magnetic fields. e⃗ and b⃗ are also perpendicular to each other and have magnitudes 3700 v/m and 3.5×10−3 t , respectively.

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.
