Sound Energy Flashcards
What is frequency?
Frequency is the number of complete wave cycles that pass a given point in one second, measured in Hertz (Hz).
How does frequency relate to pitch?
They are directly proportional . Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches.
How is amplitude related to loudness?
Greater amplitude means louder sound; smaller amplitude means quieter sound
What is wavelength in a wave?
Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough, measured in meters (m)
What is the period of a wave?
The period is the time it takes for one complete cycle of the wave to pass a given point, measured in seconds (s).
Sound is measured in
decibels
Why can sound not be heard in a vacuum
Sound requires particles and in a vacuum there are no particles
