Question 1 A light ray strikes a hexagonal ice crystal (nice = 1.30} oating in the airlnair = 1.00) as shown in the gure.All the rays shown are in the plane of the page. Which outgoing ray is the correct one? Q B 0 none of the otheranswcrs is correct 0 A O E O C O D \fQuestion 3 5 p' Forthe circuit shown, E = 6.0 V, R1 = 7.0 Q, R2 = 3.0 Q . R3 = 6.0 Q , and R4 = 12.0 Q. After operating for along time, equilibrium is established. What is the voltage across the resistor R1 at equilibrium? 0 4.2V 0 3.0V 0 none of the otheranswers is correct 0 23V 0 6.0V
