Wave Lengths
| Question | Answer |
|---|---|
| Waves | oscillations that carry energy |
| Oscillation | an up and down or back and forth motion |
| Vacuum | space that has no matter in it |
| Mechanical Waves | made by another force like a boat engine |
| Types of Mechanical Waves | longitud and laditud waves |
| Electromagnetic Waves | they are waves that do not need to travel in matter they can travel in a vacuum |
| Types of Electromagnetic Waves | light waves or radio waves |
| Wave Properties | four main characteristics of a wave |
| Amplitude | one half the distance between a waves high point and low point |
| Crest | a waves high point |
| Trough | a waves low point |
| Resting Point | middle between high and low point |
| Wavelength and symbol | measure from a point on one wave to the same point on the next |
| Wavelength Units | Frequency or Hertz HZ |
| 3 Ways to measure wavelength are | Wave |
| Frequency | measurement of wave lengths in HZ |
| Units for Frequency | Hertz HZ |
| Wave Speed | how up and down a wave is if it goes up and down like 10 times in 10 seconds it higher HZ |
| Wave Speed Units | Hertz |
| Wave Speed Equation | v=f x λ |
| Medium | middle point of a wavelength |
| Reflection | light bouncing back or off a surface |
| law of reflection | law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane |
| Reflected Ray | A ray of light or other form of radiant energy which is thrown back |
| Incident Ray | a ray of light that strikes a surface |
| Refraction | waves being deflected in passing obliquely through the interface between one medium and another |
| Diffraction | bending of waves around a barrier |
| Interference | result of waves colliding into each other |
| Constructive Interference | when waves combine an form a larger wave |
| Destructive Interference | when waves collide and cancelled each other |
| Absorption | when waves go through a substance and get absorbed |
| Absorbed colors | the tendency of an object to absorb some frequencies of light |
| Reflected Colors | the color that is absorbed vs released |
| Electromagnetic | electric currents or fields |
| Spectrum | the wavelengths and frequency range of electromagnetic waves |
| Visible Light Spectrum | the segment of the electromagnetic spectrum that the human eye can view |
| Longitudinal Wave | a wave vibrating in one direction getting larger |
| Expansion | getting larger |
| Compression | being squished down or made smaller |
| Intensity | measurable amount of a property |
| Units of Sound | decibels |
| Pitch | rate of vibrations |
| Digital Signal | an electrical signal that is converted into a pattern of bits |
