Two light rays which are not coherent cannot:
Correct answer: C. Interfere
- A. Diffract
- B. Polarize
- C. Interfere
- D. All
Explanation
C is the right option because Coherence is a prerequisite for the interference of light waves. If two light rays are not coherent, they cannot interfere constructively or destructively. Therefore, without coherence, interference cannot occur between the two light waves.

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.
