A thin convex lens is made of two materials with refractive indices \(n_1\) and \(n_2\), as shown in figure. The radius of curvature of the left and right spherical surfaces are equal. \(f\) is the focal length of the lens when \(n_1=n_2=n\). The focal length is \(f+\Delta f\) when \(n_1=n\) and \(n_2=n+\Delta n\). Assuming \(\Delta n \ll(n-1)\) and \(1<n<2\), the correct statement(s) is/are,https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
