Amplitude
What does amplitude measure?
volume
What does wavelength measure?
pitch
mother dolphin
True or false: Sound waves are seen by the naked eye.
Describe what amplitude changes in the waveform
height of the wave
Describe what wavelength changes in the waveform
length of the wave or distance from peak to peak
When a mother dolphin is calling to its calf, who is the listener?
The calf/baby dolphin
What is a wave?
a pattern of energy
Draw a sound wave for a quiet sound.
wave should be short
Draw a sound wave for a low pitch sound.
sound wave should be long
What moves a lot when sound travels through water?
energy
What type of material (solid/liquid/gas) can sound travel through the least and why?
solid because the particles are all packed together and do not move freely
Draw a sound wave for a loud sound.
sound wave should be tall
Draw a sound wave for a high pitch sound.
sound wave should be short and tight
How does the sound from mother dolphin get to the baby dolphin?
The sound travels in a sound wave which makes the particles in the water vibrate and transfer energy
What changes a sound wave?
volume and pitch
The sound wave would start short and then grow taller.
Describe how a sound wave would change if the pitch changed from low to high.
The sound wave would start long and get shorter.
Why can calves recognize their mom's whistles?
Each mother dolphin has their own signature whistle that the baby dolphin memorizes from birth.
What type of material (solid/liquid/gas) can sound travel through the easiest and why?
Gas or air because the particles are the most spread out
