Phenomena handout
A.
Interference – effect produced by two waves passing
simultaneously through a region
1.
Superposition – when waves ______________________, the resultant
displacement is the algebraic sum of the individual displacements of each wave

C) Resonance – The
building up of energy by adding small amounts of
energy
in time with the ___________________ frequency of an object
Resonance Frequency – _____________________________that an object
vibrates when disturbed
Wave / Slit / Diffraction
Large differences between __________________ and _________________ causes greater diffraction
