 # Implement other required methods similarly

-
-This example defines a `Water` type which uses the Quan-Fry dispersion model and the Kopalevich scattering model
-
-## Usage
-
-Here is a simple example of how to use the package:
-
-```julia
-using CherenkovMediumBase
 
 # Define a medium (example)
 medium = Water(34.82, 4, 100, 0.005, 0.005, 0.95)
