​The picture shows an investigation setup Jaya used to model wave patterns.

Multiple Choice

What type of wave pattern will be created when the drop reaches the water?

• Plane

• Period

• Circular

• Radio

Multiple Choice

Which statement describes the movement of the wave that Jana created?

• The wave will start at a single point and move outward in all directions.

• The wave will move in parallel lines in one direction similar to stripes.

• The wave will stay in one place and move up and down.

• The wave will increase its speed as it gets closer to the side of the dish.

Multiple Select

What two things will change if Jaya adds water drops more quickly to the dish of water?

• The distance between waves will increase.

• The wave frequency will increase.

• The distance between waves will decrease.

• The wave frequency will decrease.

Multiple Select

Choose the two examples that best represent a model of oscillation.

• a guitar string that has been plucked

• a tire swing hanging motionless from a tree

• a barrel rolling down an incline

• a rubber ball dropped on a sidewalk

Multiple Select

Choose THREE features that best describe a circular wave.

• moves in all directions

• starts at a single point

• moves in one direction

• looks like circles

Multiple Select

Choose THREE features that best describe a plane wave.

• moves in one direction

• moves in all directions

• begins with a line

• looks like stripes

​Andrea used the pendulum shown to study the effect of mass and string length on the wave period of a pendulum. She recorded her data in the table.

Multiple Choice

Which conclusion is supported by the evidence in the table?

• The length of the string affects the mass of the bob.

• The mass of the bob affects the wave period of the pendulum.

• The length of the string affects the wave period of the pendulum.

• The mass of the bob affects the length of the string.
