Questions & Step-by-Step Solutions
If the object distance is equal to the focal length of a convex lens, what is the nature of the image formed?
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 converges light rays that pass through it.
Step 2: Know the terms involved. The 'object distance' is the distance from the object to the lens, and the 'focal length' is the distance from the lens to the focal point where light rays converge.
Step 3: Recognize the relationship between object distance and focal length. When the object distance is equal to the focal length, it means the object is placed at a specific point relative to the lens.
Step 4: Recall the lens formula or the behavior of light through a convex lens. When the object is at the focal point, the light rays that come from the object will diverge after passing through the lens.
Step 5: Determine where the image is formed. Since the light rays diverge, they do not meet at a finite point, which means the image is formed at infinity.
Step 6: Conclude that when the object distance equals the focal length of a convex lens, the image formed is at infinity.
