VibrationsIs when there is a sound wave going back and forth from an object.examples: playing a instrument, water drippingIt was easy.

Infrasound and UltrasoundInfra- when its a low sound and humans cant detect.-examples: elephants, whales Ultra- when its a high sound and humans can detect.-examples: doctors, bats, submarine

Pitch and intensityIs when there is a high or low sound wave.-examples: high or low pitchIs when the more intensity the bigger amplitude and the lower the intensity the smaller the amplitude.- examples: radio

Doppler effectIs the sound source of a wave.- examples:cop,firetruck,ambulance

Electromagnetic spectrumIs a scale that tells the speed of a wave.-RW,MW,IRL,VL,UV,XR,GR

Reflection and absorption Is when light or sound is reflected off an object\white.-example- mirror Is when an object sucks in or absorbs the light\black.-example: black tablewould absorb the light

Transmission When light or sound passes through an object.-example:

Transparent and translucent When you can see perfectly threw it. -example: window When you can see threw it its blurry and only can see shapes.-example: wet window

Opaque Is when you cant see through an object.-examples: a wall, house, some doors

Wavelengths A wavelength is the distance over which the waves shape repeats itself. -red, orange, yellow, green, indigo, violet-it was easy and I had no problems

Rod and Cone CellsA rod cell is a cell that allows us to see different shades of grey.A cone cell is a cell that allows us to see three colors red, blue, green.

Electric field and Electric chargeA electric field is a shield that surrounds the electric charge.A electric charge is a physical quantity of matter that causes it to experience a force when near another electrical charged matter.

Static Charge Static electricity refers to the build up of electric charge on the surface of objects.-example: a baby getting shocked

How lightings formed Lighting is formed by a build up of charges, then separation of charge and then a release of charge. Those are the three steps of how lightings formed.

Resistance and GroundWhat slows down the movement of electrons in conductors and insulators.I understand this lesson and I have no problems. Is an allows lightning and electricity to move into the ground.-example: lightning rod Electric circuits Series is when there is only one path for electricity to flow.-examples: light, oven, phone charger Parallel is when there is multiple paths for electricity to flow.-examples: school, construction site

Switch and Voltage SourceIs what turns on or off the circuit.-example: light switchIs the power source of the circuit.-example: a battery

Conductor and Power SourceIs a material that the electricity runs threw.-example: metal The power source is what ever the voltage source is powering.-example: tv, radio, microwave

Electricity Insulator doesnt let electricity or heat pass threw.Conductor allows heat and electricity to pass threw.
