A Oil reflects the light and the lens of our eyes break it into component colors.Oil reflects the light and the lens of our eyes break it into component colors.

B Oil has a very high index of refraction, trapping and reflecting the visible spectrum. Oil has a very high index of refraction, trapping and reflecting the visible spectrum.

C The components of white light are refracted at different angles due to their various wavelengths. The components of white light are refracted at different angles due to their various wavelengths.

D The visible spectra of white light travel at different speeds, reaching the oil separately so we see the component colors. The visible spectra of white light travel at different speeds, reaching the oil separately so we see the component colors.

Answer 1

The best explanation for the observation of various colors when sunlight strikes oil on the surface of water is:

C: The components of white light are refracted at different angles due to their various wavelengths.

This phenomenon is typically a result of thin film interference, where different wavelengths (colors) of light are refracted and reflected at slightly different angles due to the varying thickness of the oil layer, creating a spectrum of colors.
