Sound Wave Basics
This is the highest point of a sound wave.
Crest
Pitch is determined by this property of a wave.
Frequency
Light is made of tiny packets of energy called these.
Photons
A material that lets all light pass through clearly is called this.
Transparent
This measures how tall a wave is and relates to how loud a sound is.
Amplitude
A low-pitched sound has this type of frequency and wavelength.
Low frequency and long wavelength
Arrange visible light from longest to shortest wavelength.
ROGBIV
A material that lets some light through but scatters it is called this.
Translucent
This is the distance between two crests or two compressions.
Wavelength
A high-pitched sound has this type of frequency and wavelength.
High frequency, short wavelength
The type of electromagnetic waves that come just after visible light (longer wavelengths) are these.
Infrared
A material that does not allow light to pass through is called this.
Opaque
Sound waves with greater intensity are louder because they have this larger wave feature.
Amplitude
As you drive away from a siren, the pitch you hear does this.
Decrease/gets lower
The waves with the shortest wavelengths in the electromagnetic spectrum are these.
Gamma rays
A green leaf appears green because it reflects green light and absorbs this color.
All of them besides green.
If a sound wave has a small amplitude, this is how it will sound.
Quiet
When light is redirected as it passes through particles or molecules, this process occurs.
