| Question | Answer |
|---|---|
| diffraction | when the size of the aperture or obstacle is of the same order of magnitude as the wavelength of the incident wave. |
| refraction | the fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density. |
| standing wave | combination of two waves moving in opposite directions, each having the same amplitude and frequency |
| reflaction | he conceptual operation of inverting a system or event with respect to a plane, each element being transferred perpendicularly through the plane to a point the same distance the other side of it. |
| constructive interference | when two waves come together and make a bigger wave |
| destructive interference | when two wave come together and make a smaller wave |
| principle of superposition | layers of rock are superimposed, or laid down one on top of another |
| beats | repeated waves moving at the same speed |
| interference | the combination of two or more electromagnetic waveform to form a resultant wave in which the displacement is either reinforced or canceled. |
| nodes | a point at which the amplitude of vibration in a standing wave system is zero. |
