1. The problem statement, all variables and given/known data Can partial reflection-partial refraction occur with all waves (ie. other than light)? 2. Relevant equations 3. The attempt at a solution My textbook constantly refers to light and apparently so does Google. "For still larger incident angles there is no refraction at all,with all the wave energy being reflected; this behaviour of light is referred to as total internal reflection. This phenomenon is analogous to the total internal reflection of light." First it says that the behavior of light is referred to as total internal reflection and then it says it is analogous to the total internal reflection of light, so it seems that it can apply to all kinds of waves. Also, this chapter of my textbook is not specifically for light, its just a general introduction to waves in two dimensions.
