What is REFLECTION?
the separation out of waves as they pass through an obstacle or opening
the transfer of energy of a wave into a medium as the wave passes through
when waves bounce off the surface of an object in one direction
when waves bounce off the surface of an object in multiple directions
What is REFRACTION?
the separation out of waves as they pass through an obstacle or opening
when waves bounce off the surface of an object in multiple directions
when waves pass through a medium
the bending of light as it changes speed moving from one medium/material to another
What is DIFFRACTION?
the separation out of waves as they pass through an obstacle or opening
the bending of light as it changes speed moving from one medium/material to another
when waves pass through a medium
the transfer of energy of a wave into a medium as the wave passes through
What is TRANSMISSION?
when waves bounce off the surface of an object in one direction
when waves pass through a medium
when waves bounce off the surface of an object in multiple directions
the separation out of waves as they pass through an obstacle or opening
What is SCATTERING?
when waves bounce off the surface of an object in multiple directions
when waves bounce off the surface of an object in one direction
the transfer of energy of a wave into a medium as the wave passes through it
when waves pass through a medium
What is ABSORPTION
the bending of light as it changes speed moving from one medium/material to another
when waves bounce off the surface of an object in multiple directions
the transfer of energy of a wave into a medium as the wave passes through it
the separation out of waves as they pass through an obstacle or opening
