MCQ
Which of the following is wrong for interference fringes?
  • A
    Fringes are due to limited portion of wave front.
  • B
    All bright fringes are equally bright.
  • C
    Distance between two consecutive fringes is constant.
  • D
    Fringes are due to the use of coherent sources.
✓

Answer

  1. Fringes are due to limited portion of wave front.

Explanation:

Statements B,C and D are correct whereas the statement "Fringes are due to limited portion of the wave front" is incorrect.

Interference fringes are formed due to the whole portion of wave front.
