Term | Definition |
---|---|
Wave | a disturbance that transfers energy from place to place |
Energy | the ability to do work |
Medium | material through which a wave travels |
Mechanical waves | travel through gases, liquids or solids |
Vibration | repeated back |
Amplitude | maximum distance that the particles of the medium carrying the wave move away from their resting position |
Wavelength | distance between 2 corresponding points (crest to crest, trough to trough) |
Frequency | the 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 |
Crest | The high point of a wave |
Visible Light | Electromagnetic waves that you can see |
Opaque | material that reflects or absorbs all light that strikes it |
Primary colors | Three colors that can be combined to make any other color |
Damping | a decrease of amplitude due to friction or other forces |
Electromagnetic spectrum | complete range of electromagnetic waves placed in order of increasing frequency |
Primary colors of light | Red, Green, and blue. When all mixed together it creates white light |
Trough | The low point of a wave |
Plane mirror | a flat sheet of glass that has a smooth silver colored coating on one side |
Concave mirrors | a mirror with a surface that curves inward like the inside of a bowl |
Convex mirrors | a mirror with a surface that curves outward |
Resting position | is the position in which the wave would sit if there was no disturbance moving through it. |
Electromagnetic waves | transfers electric and magnetic energy |
Angle of incidence | the angle that an incident light or ray makes with a perpendicular to the surface at the point of incidence |
Refraction | bending of light waves due to change in speed |
Lens | a curved piece of glass or other transparent material that is used to refract light |
Law of reflection | the angle of incidence equals the angle of reflection |
Convex lens | lens that are thicker in the center than the edges |
Concave lens | lens that are thinner in the center than the edges |
