Diffraction is a special type of
Correct answer: C. Interference
- A. Polarization
- B. Reflection
- C. Interference
- D. Refraction
Explanation
C is the right option because Diffraction is a phenomenon related to the bending of waves around obstacles or through narrow openings. It is a special type of interference that occurs when waves encounter obstacles or slits comparable in size to their wavelength.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
