A wave can make a leaf bob up and down on the water, but it cannot move the leaf toward the shore. This is because waves transfer only

• mattter.

• energy.

• media.

• crests.

If a wave was traveling at a certain speed and its frequency is cut in half, what would happen to the wavelength of the wave?

• The wavelength would be halved.

• The wavelength would produce a standing wave.

• The wavelength would remain the same.

• The wavelength would be doubled.

• through compression

• by a combination of waves

A section of a longitudinal wave where the particles are crowded together is called a

• rarefaction.

• compression.

• vibration.

• surface wave.

When the crest of one wave overlap the crests of another wave or waves, which of the following occurs?

• diffraction

• destructive interference

• constructive interference

• resonant frequencies

After collecting data, you can analyze it by

• sending it out to other scientists for review.

• posting it on a Web site and asking for analysis.

• running the experiments again until it makes sense.

• doing calculations and organizing the results into graphs.

A conclusion at the end of a scientific investigation

• can be that your results either support or do not support your hypothesis.

• can be that your results have proven your hypothesis beyond any doubt.

• usually will not give you any guidance in deciding what to do next.

• is usually the final word on the subject until someone proves otherwise.

Once you’ve asked questions and formed a hypothesis, you are ready to

• formulate a scientific theory.

• draw conclusions.

• analyze data.

• conduct experiments.
