The ball pool presents a typical behavior of the particle. Making an analogy with the ball, the light, reflectingit behaves as a particle. However, we speak of dual nature of light, ie, light can also be viewed as a wave. So worth a question that other phenomena light displays that reveal their wave nature? Interference and Diffraction The phenomena typically wave, interference and diffraction, were observed and surveyed by the English physicist Robert Hooke and the Italian Jesuit Francesco M. Grimaldi, respectively. Probably you have ever watched a musical show and should have realized that the sound is felt in different intensities. Why does this happen? The production of a wave is associated with a disturbance occurring at a certain instant. For example, when we throw a stone into the water, we perceive a circular motion. When provoke a movement back and forth on a string, we are also producing a wave. A process is characterized by the wave propagation speed of the waves, the frequency and length. The frequency of a wave depends only on the emitting source, the amplitude and wavelength also depends on the environment where this propagates. It is worth mentioning that the amplitude of a wave depends on the instant the wave is observed, since the spread in material resources is accompanied by damping as a result of energy transfer to the medium, that is, energy loss. The result of this decrease is observed in the dampening wave amplitude. When we have a number of sources which produce waves of the same frequency and wavelength, we can associate this set coherence since its pulses are produced simultaneously, ie in phase. If the pulses from two distinct sources reach a point in the same time (in phase) or lag (lagged), its effects can be added or subtracted, producing what is called interference. When their effects are added, the constructive interference is considered and when, instead, subtract its effect is considered destructive. Sound, constructive interference are identified by the increase in intensity of certain regions, and destructive where its intensity is decreased. (Adapted from: GREF, 1996.)

Lopta pool predstavlja tipičan ponašanje čestica. Izrada analogiju s loptom, svjetlo, odražavajućise ponaša kao čestica. Međutim, govorimo o dvostrukom prirode svjetlosti, odnosno, svjetlo također se može promatrati kao val. Dakle, vrijedi pitanje:što drugi fenomeni svjetlo zasloni koji pokazuju njihovu valnu prirodu? Smetnje i Difrakcija Pojave obično val, smetnje i difrakcije, promatraju i pregledan od strane engleskog fizičara Robert Hooke i talijanske isusovac Francesco M. Grimaldi, respektivno. Vjerojatno ste ikada gledali glazbeni show, a trebali su shvatili da je zvuk je osjetio u različitim intenzitetima.Zašto se ovo dogodilo? Proizvodnja vala je povezan s poremećajem koji je nastao u određenom trenutku. Na primjer, kada smo baci kamen u vodu, mi percipiramo kružnim pokretima. Kad izazvati kretanje naprijed i natrag na konac, također smo proizvodnju val. Proces se odlikuje brzinom vala valova, učestalost i dužina. Učestalost vala ovisi samo o emitira izvor, amplituda i valna duljina se također ovisi o okruženju gdje se to propagira. Vrijedno je spomenuti da je amplituda vala ovisi o trenutku val promatra, budući da je širenje u materijalnim sredstvima prati prigušivanje kao rezultat prijenosa energije na mediju, koji je, gubitak energije. Rezultat tog smanjenja je promatrana u prigušivanja val amplitude. Kad imamo niz izvora koje proizvode valovi iste frekvencije i valne duljine, možemo povezati ovaj set koherentnost a, jer su impulsi proizvedeni istovremeno, odnosno u fazi. Ako impulsi iz dva različita izvora doći do točke u isto vrijeme (u fazi) ili zaostajanje (zaostaje), njeni učinci mogu se dodati ili oduzeti, proizvoditi ono što se zove smetnje. Kada se njihovi učinci se dodaju, konstruktivne interferencije se smatra i kada, umjesto toga, oduzmite njegov učinak smatra destruktivnim. Zvuk, konstruktivne interferencije su identificirani porastom intenziteta pojedinim regijama, i destruktivno u kojoj je njezin intenzitet smanjen. (Preuzeto iz:.
