Wave Basics
What is a wave?
A disturbance that transfers energy from one place to another.
Can sound travel through air?
Yes
Light is part of what spectrum?
Electromagnetic spectrum
What does the R in ROYGBIV stand for?
Red
This describes how many waves pass a point each second.
What is frequency?
What is the highest point of a transverse wave called?
Crest
Sound waves are primarily what type of wave: transverse or longitudinal?
Longitudinal
Does light require a medium such as air to travel?
No
What does the V in ROYGBIV stand for?
Violet
A sound with a high frequency will have this type of pitch.
What is a high pitch?
What is the lowest point of a transverse wave called?
Trough
What property of a sound wave determines its pitch?
Frequency
Light waves are what type of wave: transverse or longitudinal?
Transverse
Put these in visible-spectrum order: blue, red, yellow, green.
Red, yellow, green, blue
This part of a wave is related to the energy or intensity of the wave.
What is amplitude?
What is the distance between two neighboring crests called?
Wavelength
What generally happens to perceived loudness when the amplitude of a sound wave increases?
It gets louder.
What happens when light bounces off a surface?
Reflection
Which visible color has the longest wavelength?
Red
If a sound wave’s amplitude increases, the sound will generally be perceived this way.
What is louder?
What happens to wavelength when frequency increases if wave speed stays constant?
Wavelength decreases.
Why can't sound travel through the vacuum of outer space?
Sound requires matter/a medium to travel through.
What is the bending of light as it passes from one material into another called?
Refraction
Which visible color has the highest frequency?
Violet
A low-pitched sound has fewer vibrations per second than a high-pitched sound. This means it has this type of frequency.
What is a lower frequency?
