When two waves that are out of phase from each other interact with one another, the result is (a) the wave with the positive values dominates (b) the cancellation of both waves via destructive interference (c) a wave with double amplitude via constructive interference (d) an unstable wave that reverses back to the initial waves (e) None of the above
Homework Answers
- Actually interference of waves is the combinations of two waves when they approach each other.
- But this combination of waves can be in phase or out of phase.
- in phase interference is the addition of amplitudes of both i.e crest meets with crest and rough meets with trough of the other wave exactly.
- Out of phase , the crest and troughs meets oppositely and their amplitudes cancels out resulting zero amplitude.
-------------------------------------------------------------------------------------------------------------------
out of phase interference produces a destructive wave , called as destructive interference.
Options -- b ,
option d can be considered when given as -- after destructive interference they move away from each other. . This happens in both constructive and destructive interference. In constructive interference a stable wave reverts and in destructive interference an unstable. wave.

Option C is the characteristic of constructive interference.

Question 3 NAME: The circuit shown below contains two switches which open and close perfectly out of phase with one another (only one is open at any given time, and once one closes the other immediately opens, and vice-versa). The switches alternate at a frequency of 10kHz, and each switch spends 50% of the time open and 50% of the time closed (ie, each switch is open for 100 microseconds and then closed for 100 microseconds). The...

Notes Two players will face each other. They each decide independently to "cooperate" or "cheat". If they both cooperated, they each win two points. If they both cheated, nobody wins anything. one cheats, the cheater gets +3 and the cooperator loses a point. That wasn't very kind! One turn is defined as each player making a choice, and winning or losing some points as a result. Shared history against this player is available...
