Describe why using this simulation is a useful method for studying projectiles. Clearly identify the error sources the simulation eliminates or minimizes. Also, run some tests to determine how well the simulation represents projectile motion and identify some limitations of the simulation.

c)as speed changes, wavelength and frequency change.

everything changes!

their crystal patterns have been disrupted by stress

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
