Drinking water helps maintain nearly all processes of the human body and <em>homeostasis. </em>Further, drinking water helps,
- Digestion
- Absorption
- Circulation
- Saliva and mucus production
- Thermoregulation/homeostasis
- Lubrication of joints
- Boosts integumentary health.
- Helps in excretory systems
- Prevents dehydration of cells
- Reduces chance of hangover from alcoholic drinks.
- etc,
Succinctly, it is VERY important to drink water! Water is the source of human life and without water, we cannot survive.

To solve this problem it is necessary to apply the concepts related to the condition of path difference for destructive interference between the two reflected waves from the top and bottom of a surface.
Mathematically this expression can be described under the equation

Where
n = Refractive index
t = Thickness
In terms of the wavelength the path difference of the reflected waves can be described as

Where
\lambda = Wavelenght
Equation the two equations we have that


Our values are given as
Wavelength of light



Therefore the minimum thickness of the oil for destructive interference to occur is approximately 34.0 nm
