Q: What is the nature of the image formed by a convex lens when the object is placed at a distance greater than twice the focal length?
Solution: When the object is placed beyond 2f, the image formed by a convex lens is real and inverted.
Steps: 7
Step 1: Understand what a convex lens is. A convex lens is thicker in the middle and thinner at the edges, and it converges light rays that pass through it.
Step 2: Know the focal length (f) of the lens. The focal length is the distance from the lens to the point where light rays converge.
Step 3: Identify the distance '2f'. This is twice the focal length and is an important point for image formation.
Step 4: Place the object at a distance greater than '2f'. This means the object is farther away from the lens than twice the focal length.
Step 5: Use the lens formula to determine the nature of the image. When the object is beyond '2f', the image formed is real, meaning it can be projected on a screen.
Step 6: Determine the orientation of the image. The image is inverted, which means it is upside down compared to the object.
Step 7: Conclude that when the object is placed at a distance greater than '2f', the image formed by the convex lens is real and inverted.
