ALL ABOUT REFLECTION (LAW & SUCH...

• Reflection: is the bouncing of light once it reaches a surface without absorbing it
• TERMS USED IN REFLECTION ARE:

  • Incident ray is the ray of light that hits the surface/boundary
  • Refracted ray is the one that bounces back
  • Normal line is perpendicular to the reflecting surface
  • Angle of incidence and angle of reflection are the angles formed by the two rays respectively with normal line.
• Law of reflection states two:

  1. angle of incidence and angle of reflection lies on the same plate.
  2. angle of incidence and angle of reflection are equal.

  A) angle of reflection

  B) reflected ray

  C) i=r

  D) angle of incidence

  E) incident ray

  F) normal line

  
• • Specular/regular reflection occurs when light strikes a smooth surface.
  • Diffuse/irregular reflection occurs when light strikes a rough surface
• PARTICLE NATURE OF LIGHT

  light is considered as a wave since it's a part of electromagnetic wave. however, when light strike a metal, photoelectric effect happens known as the emission of electrons.
• PARTICLE NATURE OF LIGHT

  • Scientist said that light is made up of photons, relating to reflection and refraction of light
