Use the following photoelectric graph to answer the question: Photo electric Effect for a Photomis sive Metal NA Kinetic Energy (en) Frequency (E14 Hz) If the incoming photon had a frequency of 2.0 E14 Hz, would you have a photo-electron ejected? (5 points)​

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.
