100

ROYGBIV

What is the visible colors of the EM spectrum?

100
The most common unit used to express loudness.
What is a decibel?
100
The maximum distance the particles in a wave vibrate from their rest positions.
What is amplitude?
200
A material in which charges cannot easily move.
What is an insulator?
200
Any material that attracts iron or materials containing iron.
What is a magnet?
200
The very narrow range of wavelengths and frequencies in the EM spectrum that humans can see.
What is visible light?
200
A reflected sound wave.
What is an echo?
200
A substance through which a wave can travel.
What is a medium?
300
The buildup of electric charges on an object.
What is static electricity?
300
The force of repulsion or attraction between the poles of magnets.
What is magnetic force?
300
The entire range of EM waves.
What is the electromagnetic (EM) spectrum.
300
Occurs when an object vibrating at or near a resonant frequency of a second object causes the second object to vibrate.
What is resonance?
300
A disturbance that transmits energy through matter or space.
What is a wave?
400
The opposition to the flow of electric charge.
What is resistance?
400
The parts of a magnet where the magnetic effects are strongest.
What are the poles?
400
When light bounces off an object.
What is reflection?
400
The bending of sound waves around barriers or through openings.
What is diffraction?
400
The result of two or more waves overlapping.
What is interference?
500
A method of charging an object that occurs when charges in an uncharged object are rearranged without direct contact with a charged object.
What is induction?
500
The three magnetic elements.
What are iron, cobalt, and nickel.
500
The release of light energy by particles of matter that have absorbed energy.
What is scattering?
500
The apparent change in the pitch of a sound caused by the motion of either the listener or the source of the sound.
What is the Doppler Effect?
500
A wave that can travel through space or matter and consists of changing electric and magnetic fields.
What is an electromagnetic (EM) wave?
