Reflection

• features of reflected waves

  waves reflect off a flat surface

  smoother the surface, the stronger the reflected wave
• effects of rough surfaces

  they scatter the light in all directions - so they appear mass and not reflective
• the angle of incident =

  the angle of reflection
• when will light reflect

  if the object is opaque and not absorbed by the material - the electrons will absorb the light energy, then reemit it as a reflected wave
