<span>The distance between the sources of a two point surface
interference determines the number of lines that can be created for the nodal
and anti-nodal lines. When the sources are moved closer together, the number of
lines becomes minimal. Thus, the spaces between the lines become bigger. The

Any object that is launched as a projectile will lose speed and, as a result, altitude, as it travels through the air. The rate at which the object loses speed and altitude depends on the amount of force that way applied to it when it was launched. It is also dependent on the size and shape of the item. This is why something like, say, a football is much faster to fall to the ground than a bullet.
