Question: In a convex lens, if the object is placed at the focus, what type of image is formed? (2020)

Options:

Correct Answer: No image is formed

Exam Year: 2020

Solution:

When the object is placed at the focus of a convex lens, the rays of light emerge parallel and no image is formed.

In a convex lens, if the object is placed at the focus, what type of image is formed? (2020)

Step 1: Understand what a convex lens is. A convex lens is thicker in the middle and can bend light rays that pass through it.
Step 2: Know where the focus is. The focus is a specific point where light rays converge after passing through the lens.
Step 3: Place the object at the focus of the lens. This means the object is located at the point where light rays would normally meet.
Step 4: Observe what happens to the light rays. When the object is at the focus, the light rays that come from the object will pass through the lens and emerge parallel to each other.
Step 5: Conclude that no image is formed. Since the rays are parallel, they do not converge to form an image on the other side of the lens.
