Front

What type of interference is represented in this diagram?

Back

Constructive Interference

Front

How can the period of a pendulum be decreased?

Back

By shortening the length of the pendulum.

Front

What does it mean when an object is moving to the East?

Back

The object is moving in the direction of the East, which is to the right on a standard map.

Front

What is the amplitude of a wave?

Back

The maximum distance from the rest position to the crest or trough of the wave.

Front

Define constructive interference.

Back

Constructive interference occurs when two waves meet and combine to form a wave with a larger amplitude.

Front

Define destructive interference.

Back

Destructive interference occurs when two waves meet and combine to form a wave with a smaller amplitude or cancel each other out.

Front

What factors affect the period of a pendulum?

Back

The length of the pendulum and the acceleration due to gravity.

Front

What is the relationship between frequency and period?

Back

Frequency is the reciprocal of the period; frequency = 1/period.

Front

What is wave amplitude?

Back

Wave amplitude is the height of the wave from its rest position.
