WebFocal length: It is the distance between the center of the convex lens and the focal point. Real Image When the image formed is inverted as compared to the object, the image formed is called a real image. This type of image can be captured on a screen. WebThe focal length of the lens is the distance from the center of the lens to the spot, given to be 8.00 cm. Thus, f = 8.00 cm. 25.22 To find the power of the lens, we must first convert the focal length to meters; then, we substitute this value into the equation for power. This gives P = 1 f = 1 0. 0800 m = 12. 5 D. 25.23 Discussion

WebQuestions: 1. Not all of the images were upright in Procedure 2. The last one was inverted, and the direction of the horizontal arrow is pointing left on the screen. 2. The range of the first bi-convex lens to form a magnified real image would be the length between the object and the focal length. 3. WebPlace arrowheads upon the rays to indicate their direction of travel. 2. Once these incident rays strike the lens, refract them according to the three rules of refraction for converging lenses. The ray that passes through the focal point on the way to the lens will refract and travel parallel to the principal axis.
