Two identical light waves, propagating in the same direction, have a phase difference \(\delta\). After they superpose the intensity of the resulting wave will be proportional to
- A \(\cos \delta\)
- B \(\cos (\delta / 2)\)
- C \(\cos ^{2}(\delta / 2)\)
- D \(\cos ^{2} \delta\)
Answer & Solution
Correct Answer
(C) \(\cos ^{2}(\delta / 2)\)
Step-by-step Solution
Detailed explanation
Phase difference between the two identical waves \(=\delta\) For identical wave, \[ a_{1}=a_{2}=a \] After superposition, intensity of resultant wave…
