Which of the statements are correct with reference to single slit diffraction pattern?
(i) Fringes are of unequal width
(ii) Fringes are of equal width
(iii) Light energy is conserved
(iv) Intensities of all bright fringes are equal
Options
- A(i) and (iii)
- B(i) and (iv)
- C(ii) and (iv)
- D(ii) and (iii)
Correct answer
A. (i) and (iii)
Step-by-step solution
In single slit diffraction, fringes are unequal in width → (i) true.
Fringes are not of equal width → (ii) false.
Light energy is redistributed but conserved → (iii) true.
Bright fringe intensities are not equal (central maximum is the brightest) → (iv) false.
✅ Correct Answer: A. (i) and (iii)
