Two lightsources have intensity of light as I_(0), What is the intensity at a point where the two light waves have a phase difference of pi//3? |
|
Answer» Solution :LET the INTENSITIES be `I_(0)`. The resultant intensity is, `I=4I_(0)COS^(2)(phi//2)` Resultant intensity when, `phi=pi//3,isI=41_(0)cos^(2)(pi//6)` `1=41_(0)(sqrt(3)//2)^(2)=31_(0)` |
