Waves

Why does sound travel faster through solids than gases?

• The atoms in the solid are farther apart than the atoms in the gas.

• The atoms in the solid are closer together than the atoms in the gas.

• The atoms in the solid are smaller than the atoms in the gas.

• The atoms in the solid are larger than the atoms in the gas.

What do waves carry through objects?

• force

• sound

• light

• energy

A band has many different musical instruments. Each instrument is played differently. In which way are all musical instruments alike?

• They all send sound waves in only one direction.

• They all make sound waves with the same frequency.

• They all use vibration to make sound waves.

• They all make sound waves when ow objects strike one another.

How do the two transverse waves compare?

• Wave 2 has a longer wavelength than Wave 1.

• Wave 2 has a higher frequency than Wave 1.

• Both waves have the same wavelength.

• Both waves have the same frequency.

Which points on the wave are the trough and the crest?

• Point Y is the trough; Point X is the crest.

• Point Y is the trough; Point W is the crest.

• Point W is the trough; Point Y is the crest.

• Point W is the trough; Point Z is the crest.
