How should the table be changed to correctly distinguish between mechanical and electromagnetic waves? Earthquake waves and radiation waves need to change places. Light waves and X-ray waves need to change places. Ocean waves and X-ray waves need to change places. Sound waves and light waves need to change places. ...the answer is D

3. on your graph, the data points between the black squares are data for elements with atomic numbers 3 through 9. locate these elements on your periodic table. what term or description would you use to identify these elements with respect to the periodic table?

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.
