• middle ear

• ear canal

How can you protect your ears?

• Put cotton balls in your ears to muffle sound

• Your ears protect themselves with various external structures

• wearing ear protection devices and keeping a distance between your ears and loud sounds

• reaming 20 ft away from objects that products sounds over .73 decibles

What is sound?

• A wave that transfers tunes

• Something that is created by vibrations that produce waves of energy through matter

• air molecules that shake

• electricity and light

What is frequency?

• amount of time it takes a wave to travel.
• how much pitch a wave has.
• number of wavelengths that occur in a period of time.
• how large the amplitude of a wave is.

What type of waves are sound waves?

• Longitudinal
• Electromagnetic
• Mechanical
• Both Mechanical and Longitudinal

What part of the transverse wave does the red arrow point to?

• wavelength
• trough
• amplitude
• crest

When the frequency of a wave increases, what happens to the wavelength?

• The wavelength is not directly affected by the frequency of a wave.
• The wavelength increases.
• The wavelength decreases.
• More specific information is needed to form a conclusion about the wavelength.
