Diffraction effect is____________________?
Correct answer: C. more for a sharp edge
- A. more for a round edge
- B. less for a round edge
- C. more for a sharp edge
- D. less for a sharp edge
Explanation
Diffraction is most noticeable at a sharp edge because the abrupt boundary causes waves to spread into the geometrical shadow. A round edge produces a more gradual obstruction, so students may incorrectly choose a by assuming any larger curved boundary gives greater bending.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
