Across
- 3. Property of waves defined as the distance between the peaks of two waves.
- 5. It is a line which marks the limits of an area; related to light it is the perpendicular to the normal and it divides two mediums
- 8. The time for a particle on a medium to make one complete vibrational cycle.
- 10. can be observed by shining a ray of light through a prism.
- 11. Physical process where a radiation deviates from a straight trajectory because of the collision with an other particle. The deviation of the wave happens randomly, thus this process is different from both reflection and refraction, in which the change of the trajectory is regular and predictable.
- 12. A phenomenon in which two waves superpose to form a resultant wave of greater or lower amplitude.
- 15. bright fringe is obtained on the screen
- 16. A phenomenon which occurs when a ray of light strikes a surface. The energy from the light is transferred to the surface material. The transfer creates heat.
- 17. A transparent solid body, often having triangular bases, used for dispersing light into a spectrum or for reflecting rays of light.
- 19. The number of crests of a wave that move past a given point in a given unit of time. The most common unit is the hertz (Hz), corresponding to one crest per second.
Down
- 1. The separation of electromagnetic radiation into constituents of different wavelength.
- 2. waves of light reinforce each other
- 4. The point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position.
- 6. Phenomena which occur when a wave encounters an obstacle or a slit. In classical physics, this phenomenon is described as the interference of waves according to the Huygens principle.
- 7. This event happens when two light waves superpose with each other in a way that the crest of one wave falls on the crest of the second wave, and trough of one wave falls on the trough of the second wave (the resultant wave has larger amplitude).
- 9. A reflection or refraction of light or other electromagnetic radiation from an irregular surface or an erratic dispersion through a surface.
- 12. two waves have the same frequency, wavelength and the peaks coincide they are said to be 'in xxx', otherwise they are 'out of xxx'.
- 13. unit of measure is second. (T=1/f)
- 14. It is something that happens in a regular and repeated way; related to diffraction we can observe that the smaller the diffracting object is, the 'wider' the resulting diffraction xxx will be
- 18. this event there are 2 effects:
- 20. A line (straight or curved) that is perpendicular to the light's wavefronts. Geometric optics describes how they propagate through an optical system. Lines from each object point can be used mathematically to locate the corresponding point on the image.
