  • Reflection
    The process by which light bounces off a boundary between two media.
  • Boundary
    The interface between two different media where light can reflect or transmit.
  • Media
    Materials through which light can travel, such as air or glass.
  • Reflective Surface
    A surface that primarily allows light to bounce off, like a mirror.
  • Transparent Surface
    A surface that primarily allows light to pass through, like glass.
  • Elastic Collision
    An interaction where momentum is conserved and objects bounce off each other.
  • Law of Reflection
    States that the angle of incidence equals the angle of reflection.
  • Incident Angle
    The angle at which incoming light strikes a boundary.
  • Reflected Angle
    The angle at which light leaves a boundary after reflection.
  • Normal
    A line perpendicular to the boundary at the point of incidence.
  • Complementary Angle
    Two angles that add up to 90 degrees.
  • Internal Angles
    Angles within a triangle that sum up to 180 degrees.
  • Theta
    A symbol often used to represent an unknown angle in geometry.
