2. For the above diagram, the pinecone is 25cm from the lens and is 9.5cm tall. If the focal length is 15 cm, calculate the distance/position and height of the image. 3. A beam of light passes through the air (n=1.00) and enters a diamond (n=2.42) at an angle of incidence of 40 degrees. Use Snell’s Law to find the angle of refraction in the diamond. If the diamond is placed in a tank of water (n=1.33) and the beam of light enters the diamond at the same angle of incidence, what would be the new angle of refraction? Show all work.
