Lab Question: Reflection & Refraction (Snell's Law) experiment 1) If you conducted this experiment with a different lens, one with larger refractive index, would you find larger angles of refraction for each angle incidence? Why or why not?? 2) Without refrence to equations, explain why it's physically impossible for total internal reflection (theta= 90 degree) to occur in this experiment ????

QUESTION 3 You take an object that is 5.25 cm high and place it 31.4 cm in front of a converging lens and observe an inverted image after the lens. You measure the inverted image with a ruler, and its length is 13.7 cm. What is the focal length of the lens in millimeters? (State answer as integer and use negative sign if appropriate. Do not confuse cm and mm. Do not include unit in answer.)...
