What is reflection?

• Reflection is the bouncing  of light off the surface that it strikes on.
• Reflection is the absorbing of light off the surface that it strikes on.
• Reflection is the bending of light off the surface that it strikes on.
• Reflection is the scattering of light off the surface that it strikes on.
