c) its initial vertical velocity

d) its range

e) its maximum height

t) the time it takes to reach maximum height

g) its time of flight

I'm not sure how to find "the time it takes to reach maximum height" and its "time of flight"

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.
