Q: If the object distance is equal to the focal length of a convex lens, what type of image is formed?

Solution: When the object is at the focal length, the image is formed at infinity.

Steps: 6

Step 1: Understand what a convex lens is. A convex lens is a lens that is thicker in the middle and thinner at the edges, which can converge light rays.
Step 2: Know the terms involved. The 'object distance' is how far the object is from the lens, and the 'focal length' is the distance from the lens to the point where light rays converge.
Step 3: Recognize the scenario. The question states that the object distance is equal to the focal length of the lens.
Step 4: Recall the lens formula. For a convex lens, when the object is at the focal point, the light rays coming from the object will be parallel after passing through the lens.
Step 5: Determine where the image is formed. When the light rays are parallel, they do not converge to form an image at a specific point; instead, they appear to diverge from a point at infinity.
Step 6: Conclude the type of image. Therefore, when the object is at the focal length of a convex lens, the image formed is at infinity.
