Vibration repeated back and forth or up and down motion
Energy the ability to do work
Medium material through which a wave travels
Crest high point of a wave
Trough low point of a wave
Amplitude maximum distance that the particles of the medium carrying the wave move away from their resting position
Wavelength distance between two corresponding points
Frequency number of complete waves that pass a given point in a certain amount of time
Speed how far a wave travels in a given amount of time
Resting Position where there is no amplitude and the wave is at rest
Mechanical Waves travel through gases, liquids or solids
Damping decrease in amplitude
Electromagnetic Wave transfers electrical and magnetic energy
Electromagnetic Spectrum the complete range of EM waves placed in order of increasing frequencies
Visible Light EM waves that you can see
Opaque reflects or absorbs all the light that sits there
Primary Colors colors that can be used to make any other colors;
Primary Colors of Light red, blue, green
Angle of Incidence the angle that a straight line,ray of light, etc., meeting a surface, makes with a normal to the surface at the point of meeting
Law of Reflection the angle of incidence equal the angle of reflection
Plane Mirror a flat sheet of glass that has a smooth, silver colored coating on one side
Concave Mirror a mirror with a surface that curves inward like the inside of a bowl
Convex Mirror a mirror with a surface that curves outward like an eye
Refraction the bending of waves as they enter a new medium at an angle
