height of a wave measured from its midline
separates white light into its different wavelengths
bending of light when it changes speed as it passes through a new medium
occurs when light rays bounce off, or reflect from, a surface back to your eyes
occurs when an object takes in light waves
is the transfer of heat that occurs when one thing touches another
transfer of thermal energy as matter moves
energy that is sent out in waves
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?
A firefly is a source of light because of its light called
light and sound

an example of conduction is
rubbing your hands together to heat them.
An example of friction is
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?
