4. Explain the relation between surface roughness and effective bondable area on the example of a cosine wave (sketch the surface and explain how to model the surface area). The cosine waves amplitude is 25% of the wave length. How many percent larger is this area as compared to being totally flat (amplitude is 0% of wave length). Base your calculations on the numeric length integral for the waves length.
