100
Electric charge that has accumulated on an object.
What is Static Electricity?
100
The region around a magnet where the magnetic force acts.
What is the Magnetic Field?
100
Light speed is the speed limit of the universe, the speed at which ALL EM waves travel, 300,000,000 meters per second here.
What is empty space? also: outer space, vacuum
100
The electromagnetic radiation with the shortest wavelength.
What are gamma rays?
100
An electric motor converts electrical energy into this.
What is mechanical energy?
200
Static discharge differs from electric current because it does this.
What is lasts for only a fraction of a second?
200
Objects that keep their magnetic properties for a long time.
What are permanent magnets?
200
Oscillating electrons produce these two oscillating fields.
What are electric fields and magnetic fields?
200
Optical fibers rely on this attribute of light to send communication messages and data.
What is total internal reflection?
300
A large discharge of static electricity that is accompanied by thunder.
What is lightning?
300
Electromagnetic induction is the process of producing an electric current by moving a loop of wire through this.
What is a magnetic field?
300
Electromagnetic waves are classified as these types of waves, the same as an oscillating rope.
What are transverse waves?
300
Visible light with the largest frequency.
What is violet light?
300
Your body needs this to produce Vitamin D.
What are ultraviolet waves?
400
Current that does not reverse direction.
What is Direct Current?
400
The magnetic force of a magnet is strongest here.
What are its poles?
400
This is a massless particle that carries radiant energy.
What is the photon?
400
Visible light with the longest wavelength.
What is red light?
400
Gamma rays are dangerous to organisms because they can do this.
What is break down molecules and cells.
500
Current that reverses direction in a regular pattern.
What is Alternating Current?
500
An electrical generator uses magnets to convert mechanical energy into this.
What is electrical energy?
500
This attribute of an EM wave is what determines the energy of its photon.
What is its frequency?
500
The part of the EM spectrum that is generally used for communication.
What are Radio Waves? also: microwaves
500
If light waves change speed and bend when they pass from one medium to another, it is called this.
What is refraction?
