Electrostatics
This part of the atom is negatively charged
What is the electron
This occurs when electric charges move
These are the names for the two different regions of a magnet
What are poles? (North and South pole)
This is what we typically call the frequency of the waves of light we can see
What is color?
The color of an object is determined by the light that is this back into our eye
What is reflected?
This law of nature says that charge cannot be created nor destroyed
What is conservation of charge?
This type of object is very good at letting current pass through it
What is a conductor?
This makes it so magnets can attract each other at a distance
What is the magnetic field?
This is the speed that light travels at
What is the speed of light/c/300,000 kilometers per second?
Red, blue, and green light combine to make this "color" of light
What is white?
Voltage
This type of current occurs when electrons are sent first in one direction and then back in the other
What is alternating current?
The north pole of a magnet will repel this pole of another magnet
What is the north pole?
These types of materials let light pass through them
What are transparent materials?
This occurs when light enters a new medium and bends to go on its fastest path through that medium
What is refraction?
If two charges attract each other with a force of 4 N, this is their total force when moved twice as far away
What is 1 Newton?
If the voltage in a circuit is doubled with the resistance remaining the same, this should happen to the current
What is double the current?
This is required to have magnetic fields occur
What are moving charged particles?
These two things are needed to create light
What is an electric field and a magnetic field?
This type of lens focuses all light to a single point
What is a converging lens?
This device stores electric potential energy inside of it
What is a capacitor?
This is how the overall resistance of a circuit compares to the resistance of individual resistors in parallel
What is overall is less than the individual resistors
The "magnets" of each electron in a material need to be this to form a bar magnet we can see with our eyes
What is aligned?
This occurs when Earth is in the shadow of the Moon
What is a solar eclipse?
A rainbow occurs when rain drops do this to the white light from the Sun
What is disperse?
