Angle of Incidence

The angle an outgoing wave of light makes with the normal.


Angle of Reflection

The angle an outgoing wave of light makes with the normal.


Chemical Energy

The energy bound up in bonds between atoms in molecules.


Compression

The moment when the particles in a wave push together.Click here to reveal the

definition!

Compressional Wave

A wave in which the vibrations move parallel to the direction in

which the wave moves.


Conduction

A form of heat transfer that involves direct contact.Click here to reveal the

definition!

Conservation of Energy

A scientific law that states that energy is neither created nor destroyed in any system but

simply changes form.


Convection

The movement of fluid masses from areas of high density by low density

due to temperature or salinity differences.


Crest

The high point of a wave.Click here to reveal the

definition!

Current Electricity

Electrons flowing from a source of electrons through a conducting

medium such as metal wire.


Electrical Energy

The movement of electrons from one place to another, either in the form of static electricity or current

electricity.


Electromagnetic Spectrum

The range of electromagnetic radiation, from radio waves to

gamma rays.


Electromagnetic Wave

A wave that does not need a medium in which to travel.


Energy

Anything that has the ability to cause a change in the universe, such as a change in

the position, speed, direction, or temperature of an object.


Equilibrium Point

The fixed position about which a wave oscillates in a repeating

pattern.


Frequency

The number of waves passing a point in a specific period of time,

usually per second.


Heat Energy

The average energy of motion of atoms and molecules.


Joule

The unit of measuring work; 1J=1N x 1m


Kinetic Energy

The energy of moving atoms, particles, or objects.


Mechanical Energy

The energy of large moving object.


Normal

An imaginary line perpendicular to the surface of a reflecting

surface.


Nuclear Energy

The energy released when the nuclei of atoms are split or fused.


Parallel Circuit

An electrical circuit with at least two paths through which the current can

flow.


Potential Energy

Stored energy that can be used to do work.


Power

A change in energy or the performance of work over time.


Radiation

The movement of heat energy through electromagnetic radiation (infrared, visible light, ultraviolet,

and so on)


Rarefaction

The moment when the particles of a wave pull apart.


Resistor

An object that turns current electricity into another form of energy, such as heat, light, or

sound.


Series Circuit

An electrical circuit with only a single path for the current.


Simple Machine

A device such as the lever, inclined plane, or pulley, which requires only the application of a single force to

work.


Static Electricity

A positive or negative electrical charge on an object, capable of

causing attraction, repulsion, or an electrical spark.


Transverse Wave

A wave that oscillates perpendicular to the direction of

travel.


Trough

The low point of a wave.Click here to reveal the

definition!

Watt

The unit of power in the SI system, equal to one joule of

work in one second.


Wave Cycle

A complete oscillation of a wave.Click here to reveal the

definition!

Wavelength

The smallest distance between identical parts of a continuous wave; for example, the distance between

consecutive crests.


Work

The distance an object moves multiplied by the force that

moves it.
