NEET Physics Lenses Assertion Reason Question
Assertion (A): A convex lens combined with a concave lens results in a lens system that can be either converging or diverging.
Reason (R): The effective focal length of a lens combination is determined by the individual focal lengths of the lenses involved.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The effective focal length of a lens system is calculated using the formula for lens combinations and can result in either a converging or diverging system based on the individual focal lengths.
