NEET 2026 Physics Lens Behavior MCQ Question
Type: MCQ-conceptual-Medium-Class 12
In a concave lens, a ray of light emanating from the object parallel to the principal axis of the lens after refraction:
A
passes through 2F, which is the radius of curvature of the lens.
B
appears to diverge from the first principal focus.
C
emerges parallel to the principal axis.
D
passes through the second principal focus.
Correct Answer
Option B
Detailed Explanation
In a concave lens, parallel rays appear to diverge from the first principal focus after refraction. This is due to the lens's diverging nature.
