When a soap film on the water is seen in the daytime, it shows beautiful colours. This phenomenon is due to
Detailed Explanation:
Soap film has two surfaces (top and bottom) that reflect light. When white light hits these surfaces, waves reflected from the top and bottom surfaces overlap and interfere, causing certain wavelengths to cancel out and others to amplify, producing the vibrant colours observed.
Diffraction occurs when light bends around edges, refraction is bending due to medium change, and polarization restricts light vibrations to one plane—none explain the colour pattern in soap films.
Therefore, interference of light is responsible for soap film colours, making Option 4 the correct answer.
