Vibrations

• Is when there is a sound wave going back and forth from an object.

- examples: playing a instrument, water dripping

It was easy.

Infrasound and Ultrasound

• Infra- when it’s a low sound and humans cant detect.

-examples: elephants, whales

• Ultra- when it’s a high sound and humans can detect.

-examples: doctors, bats, submarine

Pitch and intensity

• Is when there is a high or low sound wave.

-examples: high or low pitch

• Is when the more intensity the bigger amplitude and the lower the intensity the smaller the amplitude.

- examples: radio

Doppler effect

• Is the sound source of a wave.- examples:cop,firetruck,ambulance

Electromagnetic spectrum

• Is 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 Cells

• A 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 charge

• A 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 Ground

• What 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 Source

• Is what turns on or off the circuit.

-example: light switch

• Is the power source of the circuit.

-example: a battery

Conductor and Power Source

• Is 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 doesn’t let electricity or heat pass threw.

• Conductor allows heat and electricity to pass threw.
