Questions & Step-by-Step Solutions
Which of the following statements about a convex lens is true?
Step 1: Understand what a convex lens is. A convex lens is a transparent optical device that is thicker in the middle than at the edges.
Step 2: Learn about focal length. The focal length is the distance from the lens to the point where light rays converge.
Step 3: Know the two types of images a convex lens can produce: real images and virtual images.
Step 4: Real images are formed when the object is placed outside the focal length of the lens. These images can be projected onto a screen.
Step 5: Virtual images are formed when the object is placed within the focal length of the lens. These images cannot be projected onto a screen and appear to be behind the lens.
Step 6: Conclude that a convex lens can produce both real images (when the object is outside the focal length) and virtual images (when the object is within the focal length).
