To solve the problem, we will follow these steps: ### Step 1: Understand the Geometry We have a cylindrical jar with a radius \( r = 20 \) cm and a height \( h = 20 \) cm filled with a liquid of refractive index \( \mu = 1.5 \). A bulb is located at the center of the bottom of the jar. ### Step 2: Identify the Relevant Formula The area of the liquid surface through which light passes into the air can be calculated using the formula derived from the geometry of the situation: \[ ...
