Reflection

• Waves will reflect off a flat surface
• How does smoothness affect the reflection?

  The smoother the surface, the stronger the reflected wave is
• Why do rough surfaces not reflect?

  They scatter the light in all directions, so they appear Matt and not reflective
• What is angle of incidence equal to?

  Angle of reflection
• Light will reflect if the object is opaque and not absorbed by the material

  The electrons will absorb the light energy, then reemit as a reflected wave
