Question: What happens to the image when an object is moved closer to a convex lens than its focal length? (2019)

Options:

Correct Answer: Virtual and erect

Exam Year: 2019

Solution:

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

What happens to the image when an object is moved closer to a convex lens than its focal length? (2019)

Step 1: Understand what a convex lens is. A convex lens is thicker in the middle and bends light rays that pass through it.
Step 2: Know what the focal length is. The focal length is the distance from the lens to the point where light rays converge.
Step 3: Place an object closer to the lens than the focal length. This means the object is within the focal length distance.
Step 4: Light rays from the object will diverge after passing through the lens. They will not meet on the other side of the lens.
Step 5: Since the light rays diverge, they appear to come from a point behind the lens. This creates a virtual image.
Step 6: The virtual image is upright (erect) and cannot be projected onto a screen.
