Te Whakamāramatanga o te Whakaaroaro me ngā Tauira i roto i te oranga o ia rā
Ko tētahi āhuatanga o ngā ngaru ko te whakaata. Ka horapa ngā ngaru wai moana i roto i te moana ina pā ki te toka, kātahi ka huri te ngaru, ka pērā anō te ngaru wai i roto i te kaukau wai ina pā ki te pakitara, ka huri te ngaru wai ki te taha i ahu mai ai.
Ko ngā tauira o te whakaata e pāngia ana e ngā ngaru oro ko ngā pāorooro me ngā pāorooro. Ka puta te pāorooro ina whakaatahia te oro i te mea kei te tangi tonu te pūtake oro. I te nuinga o te wā, ka puta te pāorooro i roto i tētahi wāhi kua kati. Ahakoa ka puta te pāorooro ina whakaatahia te oro i muri i te korenga o te pūtake oro e tangi. I te nuinga o te wā ka puta te pāorooro i waho, ā, kāore e whakararuraru, engari he maha ngā wā ka hoha te pāorooro nā te mea, hei tauira, ina kōrero ana tētahi i roto i tētahi rūma kua kati, ka pōuri te kōrero a te tangata nā te whakaata o te reo o te tangata mai i ngā pakitara. Hei whakakore i tēnei, he maha ngā wā, i runga i ngā pakitara o ngā wāhi kua kati pērā i ngā whare whakatangitangi, i ngā whare puoro rānei, ka tāutahia ngā ārai wiri hau e tuku ana i te oro kia kore ai e whakaatahia te oro.
Waves that propagate on ropes, strings, or strings also experience reflection. For example, a wave on a guitar string that is played by a guitarist, after propagating along the strings, will be reflected when it arrives at the knot.
When propagating, waves carry energy so that if the waves are reflected after meeting an obstacle, some energy is passed on to the barrier and some are reflected. When a sound wave hits a wall, some sound energy is absorbed by the wall and some are reflected. Likewise, when a sea wave hits a rock or ship, some energy is transferred to the rock or ship hit by the wave, and some are reflected.
The Law of Reflection
Before understanding the law of reflection, first, learn the meaning of Rays and Wavefront. When drawing two or three-dimensional waves, the concept of wavefront is used. Waves that propagate on a rope or string are one-dimensional waves, waves that propagate on the surface of the water are two-dimensional waves, and waves that propagate in space such as sound waves are three-dimensional waves.
Wavefront represents two- or three-dimensional waves that propagate, while Rays are lines that are perpendicular to the wavefront.
The Law of Reflection states that the angle of incidence is equal to the angle of reflection, as illustrated in the image below. The angle of incidence = the angle between the incident ray and the dotted line perpendicular to the reflecting surface. The angle of reflection = the angle between the reflected ray and the dotted line perpendicular to the reflecting surface.
