A flat mirror
What is a plane mirror?
These use mirrors and lenses to see far objects
What is a reflecting telescope?
This is the study of the buildup of charge, electric discharge and electric fields.
What is static electricity?
An object has a net electric charge because it has an excess or shortage of these
What is electrons?
a ____ bounces off a surface
What is reflected ray?
These lenses cause light rays to diverge
What is the concave lens?
A current is carried by
What is a conductor?
A current is stopped by
What is an insulator?
These are the two parts of the eye where light is refracted.
what is the cornea and the lens?
These form where the rays converge
What is a real image?
These have no resistance at very low temperatures
What is a superconductor?
This is caused by a large quantity of charge.
What is a strong electric field?
This cannot be projected
What is a virtual image?
light does this when it enters a new medium with a different index of refraction
What is bends?
This melts to protect a circuit
What is a fuse?
V = I R
What is Ohm's Law?
The angle of incidence equals the angle of reflection.
What is the law of Reflection?
These lenses always cause light rays to diverge
what is Concave lenses?
This depends on the if the charge is positive or negative
what is electric field direction?
this flows opposite of the electron flow
What is the current?
