Solve 2d wave equation with Finite Difference Method. Theory described in description.docx. Droplet put on the water surface to start waves. There is a decay in wave equation. conv2 function used for faster calculations.
as_colormap.m - visualization of waves as colormap.
as_surface.m - visualization of waves as surface.
refraction.m - visualization of waves with refraction
reflection.m - visualization of waves with reflection
