The blue one (top)
The green one (middle)
The reddish one (bottom)
None of them
The bottom wave
The top wave
Both waves have the same amplitude
Distance from middle line (average) to top of wave (crest)
The very top point of a wave
The very bottom point of a wave
The distance between two crests
The high frequency wave (top)
The low frequency wave (bottom)
They both have the same wavelength
The top sound wave has a longer wavelength than the bottom
The bottom sound wave would be louder than the top one
The note (pitch) of the bottom wave would be higher than the top one
Both waves have the same frequency
True
False
True
False
Sound waves can travel through a vacuum (space)
Radio waves are sound waves
Radio waves are actually part of the electromagnetic spectrum (like light)
Sound can only travel through particles like air, rocks or water
Air particles hit our eardrums
The energy of the wave penetrates our brain
The eardrum stays completely still
Wait!
Here's an interesting quiz for you.
