Class 10 - Light Quiz (Concave Lens Image Formation)

1. Where is the image formed when an object is placed at infinity in front of a concave lens?

At the focus, virtual and diminished
At the center of curvature, real and magnified
At 2F, real and inverted
No image is formed

2. What is the nature of the image formed by a concave lens for any position of the object?

Virtual, erect, and diminished
Real, inverted, and enlarged
Virtual, inverted, and magnified
Real, erect, and diminished

3. What happens to the image size when the object moves closer to a concave lens?

The image size increases slightly
The image size decreases
The image becomes inverted
No image is formed

4. What is the position of the image formed when the object is placed between the optical center and focus of a concave lens?

Between the focus and optical center, virtual and diminished
Beyond the focus, real and magnified
At 2F, real and inverted
No image is formed

5. What is a primary rule for image formation in a concave lens?

A parallel ray refracts and appears to come from the focus
A ray through the focus emerges parallel
A ray through the center bends
Light bends towards the normal
