Unit 5, Section 2: Wave Interactions

occurs when waves bounce back from a surface they cannot pass through

occurs when waves bend in a different direction as they enter a new medium

the bending or spreading of waves as they move around a barrier or pass through an opening

when the energy of a wave is transferred to the material it encounters

the interaction between waves that meet

two waves colliding, and forming a wave with an amplitude GREATER than either of the original waves

two waves colliding, and forming a wave with an amplitude LESSER than either of the original waves

a wave that appears to stand in one place

a point on a wave with zero amplitude

a point on a wave with maximum amplitude

an increase in the amplitude of a vibration that occurs when external vibrations match an object’s natural frequency
