The fact that you can see interference colors in an oil slick on a puddle gives evidence that the oll film A) has two reflecting surfaces B) is thin C) causes only 1 phase shift D) all of these E) two of these

Respuesta :

Answer:

Option A

Explanation:

The interference color in an oil slick on a puddle results from the interference  caused as a result of reflection of light waves from the top as well as from the bottom surface of the oil slick.

This causes a disparity in the path of light reflecting from the surfaces and hence the sunlight is a band of seven colors, i.e., VIBGYOR, the disparities in the path results in constructive interference of the light rays which enables us to see interference colors in an oil slick.
