Questions & Step-by-Step Solutions
Which of the following statements is true for a concave lens? (2019)
Step 1: Understand what a concave lens is. A concave lens is thinner in the middle and thicker at the edges.
Step 2: Learn how a concave lens behaves with light. When light rays hit a concave lens, they spread out or diverge.
Step 3: Know the focal length of a concave lens. The focal length is the distance from the lens to the point where light rays appear to diverge from. For a concave lens, this focal length is considered negative.
Step 4: Combine the information. A concave lens diverges light rays and has a negative focal length, which is the true statement.
