All About Sound
the transfer of energy from a vibrating object in waves that travel through matter
SOUND
The organ used for hearing
EAR
Waves that consist of vibrating electric and magnetic fields
Electromagnetic Waves
The wavelengths of light that humans can see
Visible light
The colored part of the eye, controls the size of the pupil
IRIS
matter that sound waves travel through (can be solid, liquid, or gas)
MEDIUM
The ability to sense sound energy and perceive sound
HEARING
The EM waves with the longest wavelengths and the lowest energy
Radio waves
COLOR
Fine tunes the focus of the eye
LENS
how loud or soft a sound seems to a listener
LOUDNESS
How does cupping your hands help hearing?
Helps the outer ear catch sound waves and funnel them into the ear canal
The type of light that creates vitamin D but can also cause skin cancer
Ultraviolet UV Light
An object that separates visible light into its different colors, creating a rainbow
PRISM
When nearby objects are seen clearly, but distant objects appear blurry
Nearsightedness
How high or low a sound seems to a listener
PITCH
Which part of the ear has hair-like projections that change the sound vibrations into electrical signals for the brain?
COCHLEA
The EM waves used to send cell phone signals and for RADAR technology
Microwaves
Bioluminescence
When distant objects are seen clearly, but nearby objects appear blurry
FARSIGHTEDNESS
A change in frequency of sound waves that occurs when the source of the sound waves is moving relative to a stationary listener (hint: ambulance)
The Doppler Effect
Name of the three tiniest bones in the body (and in the ear)
Hammer, anvil, and stirrup
The three ways EM waves move -- hint, one is refraction
Reflection, refraction, diffraction
The term for glowing with light due to extremely high temperature
Incandescence
Part of the eye that contains RODS and CONES which help us distinguish colors
