Waves of Sound - Mystery 3

What did the invention called the Mosquito do?

• It made very low pitched sounds that only young people could hear.

• It made very quiet sounds that only young people could hear.

• It made very high pitched sounds that only young people could hear

Higher pitched sounds

• vibrate faster than lower pitched sounds.

• vibrate slower than lower pitched sounds.

• vibrate the same way as lower pitched sounds.

Lower pitched sounds

• vibrate faster than lower pitched sounds.

• vibrate slower than lower pitched sounds.

• vibrate the same way as higher pitched sounds.

What is the difference between pitch and volume?

• Pitch is how high or low a sound is and volume is how low or quiet a sound is.

• Pitch is how loud or quiet a sound is and volume is how high or low the sound is.

• Pitch and volume mean the same thing.

When a firecracker explodes, sound travels

• in one direction towards the ground

• in all directions like a rock making waves when dropped in a puddle.

• in two directions, down and up.

A high pitched sound will have waves that are

• close together

• far apart

• really tall

High and low pitched sound waves are different in that

• they are either tall or short.

• they are either random or in a nice pattern.

• the distance between the waves is either short or long.

What is a wavelength?

• Wavelength tells you if the sound waves are squished together or spread out.

• Wavelength tells you how tall or how short sound waves are.

• Wavelength tells you how fast sound waves are moving.

How quiet or loud a sound is...

• volume

• pitch

• sound

The traveling movement created by a vibration in water or air is...

• volume

• wave

• movement
