A long, thin solenoid has 155 turns per meter and radius 1 m. The current in the solenoid is increasing at a uniform rate of 28 A/s.

What is the magnitude of the induced electric field at a point 9.5 m from the axis of the solenoid?

Express your answer in mV/m to 2 decimal places.

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.
