Reflection (physics) From Wikipedia‚ the free encyclopedia The reflection of Mount Hood in Mirror Lake. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light‚ sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected

out in the 880–950 8C temperature range and 1–50 sÀ1 strain rate range. The effect of microstructural characteristics of the deformed specimens have been studied and correlated with the test temperature‚ total strain and strain rate. A constitutive equation for the flow stress has been defined and the test conditions for a homogeneous deformation evaluated. The machine employed for testing allowed to reach very high strain rates by means of a uniform compression for long strains (until 0.9)‚ whereas
