To solve the problem of determining the power of a combination of a convex lens and a concave lens, we can follow these steps: 1. Identify the Focal Lengths: - The focal length of the convex lens (f1) is +30 cm (positive because it is a convex lens). - The focal length of the...
Answer to: A 3.0 cm tall object is 60 cm in front of a converging lens that has a 30 cm focal length. (a) Calculate the image position. (b)...
An object is at a distance of 20 m from a convex lens of focal length 0.3 m. The lens forms an image of the object. If the object moves away from the lens at a speed of 5 m/s, the speed direction of the image will be:
