Electricity
_____________________ buildup of charges on an object,but WITHOUT flow.
Static Electricity
transfer of energy by electromagnetic waves
RADIATION
waves that move a medium at right angles to the direction in which the wave travels (light)
Transverse waves
bending of light as it enters a new medium
Refraction
An electromagnet is a magnet created by an ______________current.
Electric
The movement of electrons through a wire
Current Electricity
Atoms and molecules are always in motion (**Even in a solid!)
This is a measure of the average kinetic energy of the individual particles.
Temperature
Distance from the top of one wave to the top of the next (or trough to trough)
Wavelength
when a wave hits a surface through which it cannot pass and it bounces back(an Xray looking in a mirror)
Reflection
Thermal energy is the _____________ energy of all the particles.
Total
Two or more pathways for electricity to flow in a wire and meets at a common point.
Parallel Circuit
a fire ______________ from heat out wards ,which is why you can’t feel it without touching fire.
Conducts
Convects
Radiates
Radiates
the number of waves that pass a fixed point in a given amount of time
Wave Frequency
thinner in the center than at the edges they produce a virtual image
Concave lens
the temperature at which it changes state from solid to liquid.
Melting Point
Electricity flows in only one direction and has one pathway.
Series Circuit
_________is the movement of thermal energy from a substance at a higher temperature to another at a lower temperature.
Heat
the matter takes in energy from the wave and, in doing so, lowers the amplitude.
Wave Absorption
thicker in the center than on the edges can produce real or virtual images
Convex lens
the temperature at which it changes state from liquid to solid.
Freezing Point
Usually metals that allow electricity to flow very easily from one location to another.
Conductor
Kelvin scale is the temperature scale used in physics (physics=physical in sci), What is the freezing o=point of water on this scale?
32 degrees
b) 0 degrees
c) 273 is kelvin.
C. 273 Kelvin
How much a wave moves up or down while in motion
Amplitude
a mirror reflects (bounces back) an image a lens refracts(bends) light.
lens
When a wave passes a barrier or moves through a hole it bends or spreads out (light shining out around clouds)
Diffraction
