Waves
A repeated back-and-forth or up-and-down motion
What is a vibration?
The color with the longest wavelength
What is red?
A positive charge in an atom
What is proton?
A current flowing through a wire is surrounded by a magnetic field
What is an electromagnet?
Absorbs most of the colors of the visible light spectrum except green, which is reflected
What is chlorophyll?
Mediums that waves travel through
What are liquid, gas, and solid?
A material that reflects or absorbs all of the light that strikes it.
What is opaque?
Electrons all spin in the same direction
What is magnetism?
Changing the amount of electric current that flows through an electromagnet
What strengthens or weakens an electromagnet?
Plant transport tissues
What are xylem and phloem?
Waves that travel across
What are Transverse Waves?
The angle of reflection equals the angle of incidence.
What is the Law of Reflection?
Two poles of a magnet

What is an MRI machine?
Products of photosynthesis
What are sugar and oxygen?
Where the displacement of the medium is at a minimum
What is the trough?
A measure of how much a ray of light bends when it enters that material
What is the Index of Refraction?
The area around an electric charge that experiences the force exerted by the electric charge
What is an electric force?
Wrapping a wire around a piece of iron or steel
What controls the strength of a magnet?
Mass in an isolated system is neither created nor destroyed by a chemical reaction
What is the Law of Conservation of Mass?
The medium moves parallel to the direction the waves are traveling
What are Longitudinal Waves?
Light does not pass through or reflect from material, but remains in the material as energy.
What is absorption?
An electric field moving outward
What is a positive electric field?
The measure of an electromagnetic field
What is voltage?
Unlocking the energy in the glucose
What is respiration?
