7.)  Compute the smallest thickness of the oil film that will suppress the reflection of the green light of 532 nm wavelength.

8.) Which thickness will be required to produce the next complete destructive interference of this green light in the reflection spectrum?

White light is incident on the surface of
an oil slick (thin film) on water at an angle
of 29 degrees from the normal. Given
that the index of refraction of water is
1.33 and that of the oil is 1.43,
