On a fourth down any play not resulting in a gain of at least 10 yards for a first down results in loss of possession to the other team.
In general, interference is a deliberate act, with contact, to impede a receiver from catching a pass...or an act by a receiver to prevent defensing a pass (offensive pass interference). It is most often hitting or grabbing the receiver before the pass arrives, or a receiver shoving a defender away. If the pass has not been thrown when a defensive penalty occurs, the lesser penalty of illegal contact will apply instead. The rules are different in each level of play (high school, NCAA, NFL), as are the penalties applied.

In the NFL, pass interference is a penalty where a defensive player interferes with the ability of an eligible receiver to make a catch. The penalty for pass interference is typically a spot foul, meaning the offense is awarded the ball at the spot of the foul with an automatic first down.
In both college and the NFL, personal fouls (such as unnecessary roughness, grabbing the facemask, clipping, roughing the passer/kicker) and unsportsmanlike conduct. In college, offensive pass interference is a 15 yard penalty and defensive pass interference is 15 yards if the foul occurred 15 or more yards past the line of scrimmage (otherwise, the ball is placed at the spot of the foul). In the NFL, offensive pass interference is a 10 yard penalty and, for defensive pass interference, the ball is placed at the spot of the foul.
There is no loss of energy in the system because the waves can pass through each other. For example, an interference in two light waves will cause a re-distribution of energy but none will be lost.
Automatic First DownThere shall be no interference with a forward pass thrown from behind the line, is one rule about interference. Defensive pass interference is called when a defensive player interferes with a receiver's attempt to catch the ball. If the defender makes contact with the receiver, it is pass interference, unless the contact is incidental, or done in order to make a play on the ball. For example the defensive player can knock the ball down, even if he has to contact the receiver to do it. But he cannot push the receiver, trip him, grab his arm, pull his shirt, etc. Typically referees will call pass interference if the defensive player makes contact with the receiver but is not looking back at the ball.When defensive pass interference is called, the offense receives an automatic first down, and the ball is placed where the interference occurred. If the interference occurs in the end zone, the ball is placed on the one yard line. Pass interference cannot be challenged once called.
