To solve the problem, we will follow these steps: ### Step 1: Identify the given values - Focal length of the lens (F) = 20 cm - Refractive index of the lens (μ) = 1.5 - Refractive index of water (μ1) = 1.33 - Refractive index of air (μ2) = 1.0 - Object distance from the lens (U) = -15 cm (the object is on the same side as the water) ...
