Calculate the focal length of a biconvex lens in air if the radii of its surfaces are 60 cm and 15 cm. Refractive index of glass = 1.5

Text Solution

AI Generated Solution

To calculate the focal length of a biconvex lens in air, we can use the lens maker's formula: \[ \frac{1}{f} = \mu - 1 \left( \frac{1}{R_1} - \frac{1}{R_2} \right) \] Where: - \( f \) = focal length of the lens ...
