Across
- 4. An attribute of things that result from the light they reflect, transmit or emit in so far as this light causes a visual sensation that depends on its wavelenght.
- 6. Reflection of waves or particles from a surface such that the incident rays on the surface are scattered at many angles rather than at just one angle
- 9. A substance that makes possible the transfer of energy from one location to another, especially through waves
- 11. Imaginary surface representing corresponding points of a wave that vibrates in unison.
- 12. The distance travelled by a wave in a specified context.
- 13. The way in which the energy of a photon is taken up by matter, typically by the electrons of an atom, transforming that into internal energy.
- 16. It's the magnitude, thus a scalar quantity, of the rate of change of an object's position.
- 17. It's a phenomenon that causes the separation of a wave into spectral components with different wavelengths, due to the dependence of the wave speed from the wavelength in the crossed medium. An example happens with the prism, in which visible light is separated into its different colours.
- 19. A state, or the production of a state, in which rays of light or similar radiation exhibit different properties in different directions.
- 20. In optics, it is an idealized model of light, obtained by choosing a line that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow.
- 21. The electromagnetic radiation within a certain portion of the electromagnetic spectrum.
- 22. It's a piece of transparent material that refracts light rays in such a way as to form an image. Lenses can be thought of as a series of tiny refracting prisms, each of which refracts light to produce their own image, and when they act together, they produce a bright image focused at a point.
Down
- 1. Line that marks the limits or edges of something and separates it from other things or places. So it is a dividing line between mediums.
- 2. The point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position.
- 3. A change in the observed frequency of a wave.
- 5. The process by which a beam of light or another system of waves is spread out as a result of passing through a slit of similar linear dimensions to the wavelength of the incident wave, typically accompanied by interference between the wave forms produced.
- 7. The process by which a beam of light or another system of waves is forced to deviate from a straight trajectory by one or more paths due to localized non-uniformities in the medium through which they pass.
- 8. It is when light waves move all the way through a material without being absorbed, this happens with transparent materials, which do not absorb the photon, so the light is able to pass straight through.
- 10. An electromagnetic radiation that in the Electromagnetic spectrum is situated in between visible light and X-rays. It has frequencies of about 8 × 10 to the power of 14 to 3 × 10 to the power of 16 hertz (Hz), and wavelengths from 10 to about 380 nm.
- 14. It's the change of direction of a ray or a wave after bumping into a barrier or a surface.
- 15. The position of a point in time on a waveform cycle; we can also state that two waves are "in-phase" if their interference is totally constructive, on the contrary, if two waves are "out-of-phase", their interference is destructive.
- 18. A natural or artificial process that emits a visible electromagnetic radiation.
