Question

A block is placed in front of a convex lens as shown in the figure. Choose the most appropriate image of the block from the following options:

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

For convex lenses:
- When the object is beyond \( 2F \), the image is real, inverted, and smaller.
- When the object is between the lens and \( F \), the image is virtual, upright, and larger.

Answer 1

The Correct Option is B

Step 1:
The image formation by a convex lens depends on the position of the object relative to the focal point and the lens. - If the object is placed between the focus and the lens, the image formed will be virtual, upright, and magnified.
- If the object is placed beyond twice the focal length, the image formed will be real, inverted, and diminished.
Step 2:
In this case, the block is placed in front of the convex lens at a distance beyond \( 2F \) (twice the focal length), so the image formed will be real, inverted, and diminished.
Step 3:
According to the given options, the image that fits the description of a real, inverted, and diminished image is Option 2.
