Consider the following statements about interference of light....
Consider the following statements about interference of light.
A-When crest of one wave coincides with crest of another wave at point, this point is a point of destructive interference.
B-Two coherent sources emit wave of same frequency with constant phase difference.
Choose the correct option from the following.
Options
- ABoth statements A and B are wrong.
- BStatement A is correct while statement B is wrong.
- CStatement B is correct while statement A is wrong.
- DBoth statements A and B are correct.
Correct answer
C. Statement B is correct while statement A is wrong.
Step-by-step solution
The correct option is (C).
Statement A is false as the point where two crests coincide is the point of constructive interference.
Statement B is true, because coherent sources emit waves of same frequency.
