How do sounds travel in a solid compared to air?

• Sounds travel at the same speed in both solids and air.
• Sounds do not travel in solids, only in air.
• Sounds travel slower in solids than in air due to greater particle distance.
• Sounds travel faster in solids than in air due to closer particle proximity.

Which of the following materials would likely transmit sound the fastest?

• Air

• Wood

• Glass

• Rubber

Why do sounds travel slower in gases compared to liquids?

• Gases have more energy than liquids.

• Gases have higher temperatures than liquids.

• Gases have more tightly packed molecules than liquids.

• Gases have less tightly packed molecules than liquids.

How are electromagnetic waves different from mechanical waves?

• Electromagnetic waves can travel through a vacuum (empty space); mechanical waves require a medium.

• Mechanical waves can travel through a vacuum (empty space); electromagnetic waves require a medium.

• Electromagnetic waves are slower than mechanical waves.
• Mechanical waves can travel through solid, liquid, and gas; electromagnetic waves cannot.

Changing the amplitude of a sound waves changes..

• the pitch of the sound
• the frequency of the sound
• the duration of the sound
• the loudness of the sound

Waves are created on these ropes, wave 2 shows the greatest ___.

A sound wave travels from the room into the walls.  

What happens to the wave speed and wavelength?

• The wave speeds up and then gets shorter.

• The wave slows down because the wall is more dense. The wave

  length gets longer.

• The wave slows down because the wall is more dense. The

  wavelength gets longer.

• The wave speeds up because the wall is more dense. The

  wavelength gets longer.
