1. Calculate the focal lengths for the following thin lenses made of glass of refractive index n = 1.50. The medium surrounding the lens on both sides is air. (a) Converging lens: left surface is convex (looking from the outside of the lens) of radius |r1|=20.0 cm and the right surface is flat. (b) Converging lens: symmetrical double convex lens each surface having radius |r|= 20.0 cm. (c) Diverging lens: symmetrical double concave lens (looking from the outside of the lens) each surface having radius |r| = 20.0 cm. PHYS 2426 Engineering Physics II Problem 34.8 - 1. A slide projector (remember them?) uses a lens of focal length f = 10.0 cm. The slide is placed 10.5 cm to the left of the lens and the image is projected on a screen placed to the right of the lens. (a) What type lens is needed? (b) What is the distance between the screen and the lens? (c) One slide has a picture of the Eiffel Tower that is 3.00 cm high. What is the height of the image projected on the screen? 1. Calculate the focal lengths for the following thin lenses made of glass of refractive index n = 1.50.
