Sound
This is a quick back and forth motion.
What is a vibration?
This is changing one type of energy to a different kind.
What is energy transfer?
This part of the ear acts as a funnel for sound waves
What is the outer ear?
This is the distance between a spot on one wave and the identical spot on the next one.
What is the wavelength?
Why can't you see around a corner without using a mirror?
Light moves in straight lines.
This is the measure of how loud a sound is.
What is intensity or volume?
This is the transfer of thermal energy by touching.
What is conduction?
This is the black hole in the eye that allows light in.
What is the pupil?
This is the height of the wave and measures total energy.
What is the amplitude?
Give two examples of energy transfer.
Electricity to light/sound/movement.
Heat to movement
Movement to electricity
Light to electricity
etc
This is the bouncing of sound off of an object.
What is an echo?
This is the movement of heat without the use of matter.
What is radiation?
What is the cochlea?
This is the number of waves that pass in one second.
What is the frequency?
Why do things appear broken when sticking out of water?
The light from the water is refracted while the light traveling through the air is not, so they do not line up.
What is absorption?
This is the movement of heat in liquids and gases.
What is convection?
This is the colored part of the eye that changes the size of the hole in your eye.
What is the iris?
This is a wave in which the disturbance moves perpendicular (up and down) compared to the way the energy moves.
What is a transverse wave?
Why does hearing get worse as people age?
The tiny hairs in the cochlea begin to die and more sound energy is needed to create the electrical energy for the brain.
This is the unit used to measure everyday sounds
What is the decibel?
This is the measure of the average energy in matter.
What is temperature?
This is the part of the eye that refracts light to focus it into an image in your eye.
What is the lens?
This is a wave in which the disturbance moves parallel (the same direction) as the energy moves.
What is a longitudinal wave?
What would a wave sound like with waves that are very close together and what would one sound like with peaks very far apart?
Close - high
Far - low
