| Consider the following statements. |
| 1. A soap bubble. |
| 2. Rainbow. |
| 3. Oil slick oh a wet road. |
| All three of the above give different colours, due to which of the following set of phenomena? |
A) Refraction, Interference, Reflection
B) Refraction, Scattering, Reflection
C) Interference, Refraction, Reflection
D) Interference, Refraction, Scattering
Correct Answer: C
Solution :
[c] When light shines into the bubble, it appears to change colour. Unlike those seen in a rainbow, which arise from differential refraction, the colours seen in a soap bubble arise from interference of light reflecting of the front and back surfaces of the thin soap film. Internally reflected light is the phenomenon causing the colours in an oil slick on a wet road.
