彩虹是陽光射到空氣中的水滴里發(fā)生的光學(xué)現(xiàn)象，雨后常見。形狀彎曲，色彩艷麗。 rainbow sun shines in the air drop in the optical phenomenon occurred, after the rain common. curved shapes, colorful. 彩虹是因?yàn)殛柟馍涞娇罩薪咏鼒A形的小水滴，造成色散及反射而成。陽光射入水滴時(shí)會(huì)同時(shí)以不同角度入射，在水滴內(nèi)亦以不同的角度反射。當(dāng)中以40至42度的反射最為強(qiáng)烈，形成我們所見到的彩虹。形成這種反射時(shí)，陽光進(jìn)入水滴，先折射一次，然后在水滴的背面反射，最后離開水滴時(shí)再折射一次。因?yàn)樗畬庥猩⒌?a href="/tag/626816.html" target="_blank" class="infotextkey">作用，不同波長的光的折射率有所不同，藍(lán)光的折射角度比紅光大。由于光在水滴內(nèi)被反射，所以觀察者看見的光譜是倒過來，紅光在最上方，其他顏色在下。 rainbow because the sun shines nearly round air droplets, resulting in dispersion and reflection made. sunshine will be launched into water droplets at different incident angles at the same time, the drop in reflection through various angles. among 40 to 42 degrees to the most intense reflection, we see the formation of the rainbow. the formation of such reflection, the sun drops into the first refracted once, and then drop the back of the reflection, refraction last to leave once again when the water droplets. because the water dispersion of light there is the role of the refractive index of light of different wavelengths is different than the red light blue light refraction angle large. because the light is reflected within the water droplets, so the observer to see the spectrum is reversed,
