Sound are produced from
|
Vibrations
|
Frequency refers to
|
Amount of vibration in one second (Hertz-Hz) It determines how low or high a note is (known as pitch)
|
Loudness refers to
|
The size of vibrations in one second (decibels- dB) . This is produced depending on the energy involved.
|
Sound can only travel through
|
A medium (solid,liquid,gases)
|
Speed of sound depends on
|
The density of material. Sound in solids travel fastest than sound in liquid and gases (with gases being the slowest.)
|
High Pitch
|
High Frequency
|
Larger vibrations
|
Louder the sound
|
Echo is
|
Reflected sound waves
|
Echolocation refers to
|
The use of echo to find objects and determine distances. (releases a sound and measures the time taken for it to come back) (distance accounted twice-divided by two)
