WebJul 4, 2011 · Physicist: In a way, reflection can’t really be described as particle phenomena at all. A solid object can bounce, but that’s just a flexing and un-flexing of the object . An individual particle can’t bounce the same way, but due to its wave nature it can reflect. Essentially, a reflective surface enforces some kind of restriction on the ...

Geometry - Reflection - Math is Fun
WebReflection in Math takes place when a figure makes a mirror image of itself. Reflection in Math usually of a figure takes place over either the x-axis or the y-axis. You can Reflect on … WebReflection 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 (for example at a mirror) the angle at which the wave is … WebTo reflect Triangle ABC across the y-axis, we need to take the negative of the x-value but leave the y-value alone, like this: A (-2, 6) B (-5, 7) C (-4, 4) * Please note that the process is a bit simpler than in the video because the line of reflection is the actual y-axis. If the line of reflection was something else (like x = -4), you would ... jethalal shirt design
