the index of refraction of the oil is 1.20. what is the minimum thickness t of the oil slick at that spot?

Sagot :

The minimum thickness of the oil slick at that spot is 313 nm.

The refractive index of the oil is 1.3,

  • the light from the air-oil interface will have a stage change of
  • the light for the oil-water interface will have a stage change of .

Therefore, the interface between the two rays will give two stage change or zero stage change.

The position for the constructive interface :

[tex]2 n t=m \lambda[/tex]

Where, n = refractive index of oil

          m = order

So, for the minimum thickness (i.e. m = 1)

[tex]t_{\min }=\frac{\lambda}{2 n}[/tex]

[tex]t_{\min }=\frac{750}{2 \times 1.2}[/tex]

[tex]t_{\min }=313 \mathrm{~nm}[/tex]

What is The refractive index?

A primal physical property of a substance, it is usually used to identify a particular substance, confirm its chastity, or scale its concentration is called refractive index.
