Which consequence results when laser light reflects off oil?

💡 Explanation

Colour fringes appear because constructive and destructive interference occurs due to varying oil thickness; this process modulates reflected wavelengths. Therefore, vivid colours reflecting is the outcome, rather than changes in beam properties or frequency amplification as there's no cavity.
