Echolocation

Sound waves are sent out from a source and then the location of an object is found based on the returning wave (the echo).

Amplitude (Sound)

The strength of a sound wave that determines how loud or soft it is.

Amplitude (Object Size)

The size of a sound wave that determines the size of an object through echolocation.

Frequency (Sound)

The rate at which a sound wave vibrates, responsible for how high or low a sound appears.

Study Notes

Echolocation

Sound is emitted from a source.
The time taken for the reflected sound wave to return is used to determine the object's location.
The amplitude of the returning wave indicates the size of the object.
The direction of the returning wave indicates the object's direction.

Sound Wave Properties

Sound waves are longitudinal waves.
Changes in pitch (frequency) result in changes in the sound wave.
Changes in volume (amplitude) result in changes in the sound wave.
