For the constructive interference the path difference between the two interfering waves must be equal to
Options
- A(2 n +1)
- B2 n
- Cn
- D(2 n +1) 2
Correct answer
C. n
Step-by-step solution
Phase difference, = 2 x In a constructive interference, array cc =2 n & where n =0,1,2,3, 2 n = 2 x or & x = n array
