Question: What happens to the image formed by a convex lens when the object is moved closer to the lens than its focal length?

Options:

Correct Answer: Image becomes virtual

Solution:

When the object is within the focal length of a convex lens, the image formed is virtual and upright.

What happens to the image formed by a convex lens when the object is moved closer to the lens than its focal length?

Step 1: Understand what a convex lens is. A convex lens is thicker in the middle and can bend light rays to focus them.
Step 2: Identify the focal length of the lens. The focal length is the distance from the lens to the point where light rays converge.
Step 3: Place an object in front of the lens. Move the object closer to the lens than the focal length.
Step 4: Observe the light rays. When the object is within the focal length, the light rays diverge after passing through the lens.
Step 5: Determine the type of image formed. Since the light rays diverge, they appear to come from a point behind the lens.
Step 6: Conclude that the image is virtual. A virtual image cannot be projected on a screen and is seen only by looking through the lens.
Step 7: Note the orientation of the image. The virtual image formed is upright, meaning it has the same orientation as the object.
