- 40. the change in direction of a wave passing from one medium to another or from a gradual change in the medium
- 41. phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude
Down
- 1. reflection, reflection such that the angle of reflection of the light is equal to the angle of incidence and on the opposite side of the normal to the point of incidence.
- 2. the change in direction of a wave passing from one medium to another or from a gradual change in the medium.
- 3. the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated
- 5. wave, a wave in which the particles of the medium move progressively in the direction of the wave propagation with such a gradation of speeds that the faster overtake the slower and are themselves in turn overtaken
