Waves Science
SPS9a,b,c,d,e vocab
| Term | Definition |
|---|---|
| Medium | any form of matter whose particles transport the wave's energy |
| Wave | a disturbance caused by the mechanical motion of a particle |
| Propagate | travel by the physical motion of particles |
| Sound wave | a form of a mechanical wave |
| Electromagnetic waves | waves that can travel through a vacuum |
| Mechanical waves | waves that require a medium |
| Vacuum | empty space |
| Transverse wave | a wave that oscillates in the direction that is perpendicular to it's movement |
| Longitudinal wave | a wave that oscillates in the direction that is parallel to it's movement |
| Amplitude | the maximum displacement of a wave particle from the midpoint between the crest and the trough |
| period | the amount of time for one cycle of motion to complete |
| Wavelength | the distance between two crests |
| Hertz | the peak of one cycle per second |
| Frequency | The number of wavelengths that occur in a time |
| the velocity formula | Frequency*Wavelength |
| the symbol for wavelength? | Lambda (λ) |
| Reflection is | when waves bounce off of a surface |
| an example of reflection? | Waves bounce from the mirror into your eyes when you look into it |
| If a wave is only partially reflected what happens to the leftover energy | absorbed |
| When waves travel through matter | Transmitted |
| Reflection | waves bounce off the surface at the same angle it hit it |
| Transmission | travels through the material at the same angle it entered |
| Refraction | travels through the material, but now at a different angle |
| Diffraction | travels through the material until an obstacle is encountered. The proceeds to BEND around the object and pass. |
| Absorption | does not travel all the way through the material. |
| Interference | Wave come from 2 sources and meet. They then affect each other in different ways. |
| Law of Reflection | States that the angle of reflection equals the angle of incidence |
| Angle of Incidence | Angle of which light hits the surface |
| Angle of Reflection | Angle that the light bounces off the surface |
| Refraction does what based on the density of the medium | It bends the wave |
| What is Snells Law | n1sinθ1=n2sinθ2 |
| What is Visible Light | Light that humans can see with the naked eye |
