Q: In a thin film of oil on water, which phenomenon is responsible for the colorful patterns observed?
Solution:
The colorful patterns in a thin film are due to interference of light waves reflected from the top and bottom surfaces of the film.
Steps: 7
Show Steps
Step 1: Understand that light is made up of waves.
Step 2: When light hits the thin film of oil, some of it reflects off the top surface of the oil.
Step 3: Some light also goes through the oil and reflects off the water surface below.
Step 4: The light waves that reflect from the top and bottom surfaces can overlap.
Step 5: When these overlapping light waves meet, they can combine in different ways.
Step 6: Depending on how they combine, they can create bright colors or dark areas.
Step 7: This combination of light waves is called interference, which is what causes the colorful patterns.
