Physics Question on spherical lenses

What is the lens makers formula?

A

1f=(μ+1)(1R1−1R2)\frac 1f=(μ+1)(\frac {1}{R_1}-\frac {1}{R_2})

B

1f=(μ−1)(1R1−1R2)\frac 1f=(μ-1)(\frac {1}{R_1}-\frac {1}{R_2})

C

1f=(μ+1)(1R1+1R2)\frac 1f=(μ+1)(\frac {1}{R_1}+\frac {1}{R_2})

D

1f=(μ−1)(1R1+1R2)\frac 1f=(μ-1)(\frac {1}{R_1}+\frac {1}{R_2})

Answer

1f=(μ−1)(1R1−1R2)\frac 1f=(μ-1)(\frac {1}{R_1}-\frac {1}{R_2})

Explanation

Solution

The correct option is (B): 1f=(μ−1)(1R1−1R2)\frac 1f=(μ-1)(\frac {1}{R_1}-\frac {1}{R_2}).
