Answer:
Thickness = 110.57 nm
Explanation:
Given that:
The refractive index of the lens = 1.56
The refractive index of the non reflecting coating = 1.23
The wavelength of the light = 544 nm
The thickness can be calculated by using the formula shown below as:
[tex]Thickness=\frac {\lambda}{4\times n}[/tex]
Where, n is the refractive index of the non reflecting coating = 1.23
[tex]{\lambda}[/tex] is the wavelength
So, thickness is:
[tex]Thickness=\frac {544\ nm}{4\times 1.23}[/tex]
Thickness = 110.57 nm
