Current Electricity
What is current electricity?
The flow of electrons on a path
What is a magnet?
Any material that creates a magnetic field around itself
What is in the electromagnetic spectrum
Radio waves, Microwaves, Infrared waves, visible light, Ultraviolet, x ray, and gamma ray
What is dispersion?
Dispersion is when the different colors that make up light are spread out as they refract at different angles.
What is transparent
something that lets all light through
What is a circuit
The path for electrons to flow on.
What is the Iron triad.
Iron, Nickel, and Cobalt
What is visible light?
The portion of light that humans can see.
What is Reflection
When light bounces off of an object
What is translucent
something that lets some light through
What is the difference between a parallel circuit and a series circuit?
A parallel has 2 paths, but a series only has 1 path
What is ferromagnetic?
Something that becomes magnetized in the presence of a magnet
What colors are in the visible light. (Hint, there are 7 colors)
Red, orange, yellow, green, blue, indigo, and violet
What is refraction?
When light bends as it goes through different objects
What is opaque?
Something that doesn't let light through
What is the difference between static and current electricity?
Static electricity is the rapid buildup and transfer of electrons, and current electricity is the flow of electrons.
What is a magnetic domain?
Groups of atoms all oriented in the same way in a material to make a magnetic field.
What is a photon?
A particle of light
Name an example for reflection, refraction, and dispersion
An example of reflection is a mirror, an example of refraction is microscopes, and an example of dispersion is rainbows
What converts the electrons into energy in a circuit.
The load
What are the only types of materials that have magnetic domains?
Magnetic and ferromagnetic materials.
What are cones
Cones are a part of your eye that lets you see colors
