The Ray Approximation （射线近似）in Geometric Optics （几何光学） Light travels in a straight-line path （路径）in a homogeneous （均匀的） medium （介质）, until it encounters （遇到）a boundary （边界）between two different materials. A plane wave traveling to the When light strikes a right. Note that the rays, corresponding to the direction （方 boundary, it is either 向）of wave motion （波动）, are reflected from that boundary, straight lines perpendicular （垂直） passes into the material on to the wave fronts （波前）. A wave the other side of the front is a surface （表面）passing boundary, or partially does through the points of a wave that have the same phase （相位）and both. amplitude （振幅）. Reflection of Light （光的反射） When a light ray traveling in a transparent （透明） medium encounters a boundary leading into a second medium, part of the incident （入射）ray is reflected back into the first medium.
