Sound Waves

This is what you get when sound waves are reflected, or bounce back, off of a hard surface.

• Amplitude
• Pitch
• Volume
• Echo

The speed of a sound wave depends on

• the frequency
• the medium
• both air temperature and medium
• the air temperature

What is a pitch?

• highness or lowness of a sound
• the intensity of a vibration
• the amplitude of the sound wave
• volume of sound

Material (matter) through which a wave travels

• medium
• Doppler Effect
• sound
• pitch

When a sound is louder what measurement gets bigger?

• Frequency 
• Amplitude 
• Wavelength 
• Crest

What is transported by a wave?

• air

• energy

• matter

• particles

The diagram shows a cartoon of a sound wave produced while a student is speaking.

What happens to the sound wave when the student speaks louder?

• The amplitude increases

• the wavelength will double

• the speed will increase

• the amplitude will decrease

Through which medium is it impossible to transmit sound waves?

• space

• rock

• air

• water

Sound waves travel as __________ waves.

• transverse

• electromagnetic

• longitudinal

• surface

A back-and-forth motion causing particles to move close together generates a _________.

• rarefaction

• surface wave

• transverse wave

• compression
