Waves and Energy Review

This is a wave pattern diagram for two transverse waves. How do the waves compare?

• Both waves have the same frequency.

• Both waves have the same wavelength

• Wave 1 has a longer wavelength than Wave 2.

• Wave 1 has a higher frequency than Wave 2.

Why does sound travel faster through a solid object than in the air?

• 
  The atoms in the solid object are farther apart than the atoms in the air.
• he atoms in the solid object are closer together than the atoms in the air.
• 
  The atoms are smaller in the solid object than the atoms in the air.
• The atoms are larger in the solid object than the atoms in the air.
