Sound
energy in the form of quick vibrations passing through matter
Frequency
number of waves that pass apoint in a certain amount of time
Wave Length
distance between a point on one wave and a similar point on the next wave
Pitch
how high or low a sound is
Volume
measure of how strong a sound seems to be
Amplitude
height of a wave measured from its midline
Prism
separates white light into its different wavelengths
Refraction
bending of light when it changes speed as it passes through a new medium
Reflection
occurs when light rays bounce off, or reflect from, a surface back to your eyes
Absorption
occurs when an object takes in light waves
Conduction
is the transfer of heat that occurs when one thing touches another
Convection
transfer of thermal energy as matter moves
Radiation
energy that is sent out in waves
Vibration
quick back and forth movements
the more energy it has and the louder it is.
If the amplitude of a wave is high, then....
With objects that vibrate quicker
How are higher frequencies made?
Those with smooth, shiny surfaces
What type of surface reflects light the best?
bioluminescence
A firefly is a source of light because of its light called
light and sound
energy types that travel in waves
convection
This is made when gas and liquid moves from place to place.
A momma bird warming her eggs in an nest
an example of conduction is
rubbing your hands together to heat them.
An example of friction is
speed up.
If you heat water, the motion of the particles will
Radiation does not need particles of matter to travel.
How is radiation different from conduction and convection?
The solar panels help to heat the water by absorbing the suns light entergy to heat the water.
Explain how solar panels help to heat water.
Heat travels during cunduction from the warmer object to the cooler object.
How does heat travel during conduction?
Sound occurs when objects vibrate. Sound can travel though solids as well as gas.
When youstand outside a room that has the doors and windows closed, why can you still hear sounds made?
