| Abstract: | This essay is to improve the traditional method for measuring. Convex lens focal length,and use a new measurement method of taking a laser light as source. The method is simple to read directly measured.Value of the convex lens focal length.The experimental show that this. Measured method produces more accurate results than the traditional did. |
