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.
