初中物理第一册中说:从凸镜中观察到的范围比从大小相同的平面镜中观察到的范围大, 这是为什么呢? 凸镜是球面镜的一种,以球面的外表面作为反射面.光照射到凸镜上同样遵循反射定律:
In the first book of junior high school physics, the scope of observation from a convex mirror is larger than that observed from a mirror of the same size. Why is this? A convex mirror is a type of spherical mirror and uses the outer surface of a spherical surface as a reflective surface. The illumination of the convex mirror also follows the law of reflection:
