LECTURE HANDOUT: REFRACTION OF LIGHT I. Review Each of the diagrams at right shows a ray incident on a boundary between two media. Continue each of the rays into the second medium. Using a dashed line, also draw the path that the wave would have taken if it had continued without "bending." Does the ray representing a wave "bend" toward or away from the normal when: the wave speed is smaller in the second medium? ⚫the wave speed is larger in the second medium? Faster medium Slower medium Slower medium Faster medium II. Qualitative applications of refraction A. Place a coin at the bottom of an empty can or cup. Look into the cup at the coin while your partner slowly moves the can away from you until you no longer see the coin. Now, keep your head steady while your partner gently pours water into the cup. 1. Describe your observations. Switch roles with your partner so that you each have a turn. Shown below are cross-sectional diagrams of the cup for when it was empty and when it was…
Problem Six. A 70 kg student in the figure balances a 1200 kg elephant on a hydraulic lift with diameter 2.0 m that is filled with oil which has a density of 900 kg/m³. How many 80 kg students would have to stand on the first piston in order to raise the elephant by 2.55 m? 80 kg 1200 kg 17.) (A) 5 (D) 8 (B) 6 (E) 9 (C) 7 Oil 2.0 m 5
In the accompanying figure, the rails, connecting end pieces, and rod all have a resistance per unit length of 4.52/cm. The rod moves to the left at v = 5 m/s. If B = 0.3 T everywhere in the region, what is the current in the circuit (a) when a = 6.5 cm? (b) when a = 4 cm?
