Wave Interference

Front

What is wave interference?

Back

When more than one wave meets and interacts in the same medium.

Front

What is natural frequency?

Back

The special frequency at which an object naturally vibrates.

Front

What is constructive interference?

Back

When two waves meet and their crests and troughs align, resulting in a wave of greater amplitude.

Front

What is destructive interference?

Back

When the crests of one wave overlap with the troughs of another, resulting in a wave of lesser amplitude.

Front

What is resonance?

Back

The phenomenon that occurs when an object vibrates at its natural frequency due to an external force.

Front

Give an example of resonance.

Back

Pushing a child on a swing at the right moment.

Front

What happened to the Tacoma Narrows Bridge?

Back

It collapsed due to resonance caused by wind.

Front

What is a standing wave?

Back

A wave that remains in a constant position, formed by the interference of two waves traveling in opposite directions.

Front

What is the principle of superposition?

Back

The principle stating that when two or more waves overlap, the resulting wave is the sum of the individual waves.

Front

What is amplitude in wave physics?

Back

The maximum displacement of points on a wave from its rest position.
