2005年全国高考理综第17题间接考查了垂直入射到直角棱镜斜边的单色光在直角棱镜内发生全反射的次数.首先,垂直入射的单色光在直角棱镜内发生全反射的次数与棱镜的折射率有关,而同一单色光对不同介质的折射率是不同的.我们知道棱镜一般是由玻璃制成的,而玻璃的种类很多,根据不?
In 2005, the 17th problem of the National College Entrance Examination in China examined indirectly the number of times that the monochromatic light perpendicularly incident on the hypotenuse of the right-angle prism had total reflection in the right-angle prism. First, the number of times that the normal incident monochromatic light totally reflected in the right-angle prism occurred. It is related to the refractive index of the prism, and the same monochromatic light has different refractive indices for different media. We know that prisms are generally made of glass, and the types of glass are many, according to not?
