Place the single slit wheel on the optics bench and turn the wheel to the variable slit width Slowly turn the wheel and observe what happens as the slit width increases. What did you observe happen to the single-slit diffraction pattern as the slit width was increased?

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.
