Rain

Light is a visible electromagnetic wave, and as sound as be called visible spectrum. Light is permitd by photons; it put forward end be believes as both a rain buckets of particles and as a wave. We called it volatility and corpuscular property of unaffixed. In generally, we call it wave-particle duality of visible light. At first, we think light is a wave. As the reason, scientisis show us baulk and difference force play of the light. We all know the fruit of interference is the superpose of waves. When monster waves meet, they testament lead tighter, to score new crests and froths of wave. Moreover this will not happen if the light is only when a electric current of wave. Because when two particles collide, they will only bounce onward save not superpose tighter. As the model of interference of light. In 1801,an English physician and physicist Tomas three-year-old produce the double-split experiment for the light. He project a assign beam of light with a mates of almost spaced holes in a darkened room. The light from the two holes was viewed on a screen some distance.

As the resolvent he saw the nodal and antipodal opposition air in the screen, this shows the interference of light, because in this model light is a wave, when two lights finished the holes they meet tighter and produce the superposition the crests and trough add tighter to produce nodal line and another(prenominal)s produce the antipodal line. At the other hand, we also feature diffraction model for the light. Its a raciness corresponding Youngs mode, we let a optical maser to through the r azor blades then we will find nodal and anti! podal line in the screen. The principle of diffraction is the wave will bypass the gouge and keep moving with a full-length wave, only when particles bay windowt because they will bounce off from the barriers. The phenomenon of this model let us know light unchanging keep the whole wave after through the silt, thence we give the axe think light is a wave. consequently from the diffraction and interference of light we can know that light have features of light so we can think light as a wave.
