Question

An object placed between the principal focus and center of curvature of a convex lens forms an image:

• A. beyond the center of curvature
• B. at infinity
• C. at the principal focus
• D. between principal focus and center of curvature

Hint:

Object position and image characteristics for a convex lens: - Beyond 2F: Real, inverted, diminished, between F and 2F - At 2F: Real, inverted, same size, at 2F - Between F and 2F: Real, inverted, magnified, beyond 2F - At F: Real, inverted, highly magnified, at infinity - Between optical center and F: Virtual, erect, magnified, on the same side as the object

Answer 1

The Correct Option is A

Step 1: Recall the image formation rules for a convex lens.
The position of the image formed by a convex lens depends on the object's position relative to the focal point (F) and the center of curvature (2F).
Step 2: Analyze the case where the object is between F and 2F.
When the object is placed between the principal focus (F) and the center of curvature (2F) of a convex lens, the image formed is real, inverted, and magnified.
Step 3: Determine the location of the image.
Ray diagrams show that when the object is between F and 2F, the refracted rays converge to form an image beyond the center of curvature (2F)on the other side of the lens.
