They have a focal length, and where an image is formed depends on a combination of the focal length and the distance between the object and the lens.
透镜有焦距，而影像形成的位置，取决于焦距及物体与透镜距离的组合。

17.
a three-dimensional closed surface such that every point on the surface is equidistant from the center.
表面上每个点到中心的距离都相等的一种三维的闭合表面。
18.
Since, point lights have position also, the distance from the surface to the light also affects the intensity. This is known as distance attenuation.
因为，点光源有位置，所有光到达表面的距离会影响到光照亮度。这让我们了解到距离衰减。
