What is matter (a medium).
An animal that uses sound to detect objects in it's environment
what is a bat, dolphin, whale
Disturbances of electric and magnetic fields that travel through space, carrying energy at the speed of light without needing a medium.
What is electromagnetic wave
A sound wave is this type of wave.
What is a longitudinal.
This part of the ear contains fluid and tiny hairs that convert mechanical energy into nerve signals.
What is the cochlea
What waves transfer
These are the three tiny bones in the middle ear that act as an amplifier.
What are the hammer, anvil, and stirrup (ossicles)?
