A thin convex lens and a thin concave lens are kept in contact and are co-axial. Which of the following statements is correct for this combination of two lenses?
behaves as concave lens if \( |f_{\text{convex}}| > |f_{\text{concave}}| \)
behaves as concave lens if \( |f_{\text{convex}}| < |f_{\text{concave}}| \)
behaves as convex lens if \( |f_{\text{convex}}| > |f_{\text{concave}}| \)
Focal length of the lens system will change if the positions of two lenses are interchanged.
