Difference between Constructive interference and destructive interference
Interference of light is an interesting topic in a wave optics. Interference is a phenomenon which occurs when a two wave of light are meet each other while traveling from the same medium. There are two types of interference one is constructive interference and another is destructive interference. In the constructive interference the crest of the one wave is meet with the crest of the another wave then constructive interference is takes place. In the destructive interference the crest of the one wave is meet with the trough of the another wave then destructive interference is takes place. The difference between constructive interference and destructive interference is as follows.
Constructive Interference | Destructive Interference |
1) When the crest of the one wave is meet with the crest of the another wave ( or trough to trough) then constructive interference is takes place.
2) In the constructive interference when two waves meet each other the two waves are add up each other. 3) The condition for the constructive interference is that the phase difference between two waves must be zero. 4) The intensity of waves is increase in the constructive interference. 5) The waves in the constructive interference are in phase. |
1) When the crest of the one wave is meet with the trough of the another wave then destructive interference is takes place
2) In destructive interference when two waves are meet each other they cancel out each other. 3) The condition for destructive interference is that the phase difference between superimposing waves is 180°. 4) The intensity of light wave is decrease in the distructive interference. 5) The waves in the distructive interference are in out of phase.

Your English is not too good, at some point I got confused
Elizabeth We will try to improve content definitely.
Thank You
Easy and simple good easy to understand
