mechanical waves (examples)
earthquakes (through Earth), ocean waves (through water), sound waves (through air)
electromagnetic (EM) waves (examples)
EM waves given off by the vibrations of atoms (heat).
The EM waves detected by heat-vision goggles.
When an object or wave hits a surface through which it cannot pass, it bounces back.
The bending of a wave as it moves from one substance to another.
the bending of waves around an edge or corner (also occurs when waves pass through a narrow opening)
occurs when two waves line up combine to make a wave with a larger amplitude
occurs when two waves are at opposite heights and combine to cancel out partly or entirely
light from a mirror, echoes
glasses/contact lenses, a straw looks broken when you look at it in a glass
sounds can be heard from behind an object, light will spread out to fill up a room
