Soap films are thin layers of liquid usually water-based surrounded by air in the sunlight colours are visible on the surface of them due to
Correct answer: D. Interference of light
- A. Scattering of light
- B. Dispersion of light
- C. Diffraction of light
- D. Interference of light
Explanation
The correct answer is interference of light. In soap films, colors are visible due to the interference of light. When light reflects off the different surfaces of the soap film, the waves can overlap and interfere with one another, creating the vibrant colors seen. Other options like scattering, dispersion, and diffraction involve different mechanisms that do not primarily cause the colorful effects observed in soap films.

About Superposition and Interference
Superposition states that overlapping waves produce a resultant displacement equal to the algebraic sum of their individual displacements. Interference covers constructive and destructive interference, phase difference, path difference, coherent sources, and conditions for maxima and minima. It differs from diffraction, which involves spreading around openings or obstacles.
