ECE 414 HW #1 Due: 1-25-2011 1. You are at an aquarium, looking down at an angle of 15° through 2 rows of tanks – one containing reptiles (in air), and the other containing fish (in water). Both types of tanks are made of glass (n = 1.5). As shown in the picture, air and water have refractive indices of n = 1.0 and n = 1.33, respectively. Use the picture to answer the following questions. a) What is θ r (angle of reflection) in both scenarios? b) What is θ t1 (angle of transmission into glass) for both scenarios? c) What is θ t2 (angle of transmission into air or water) for both scenarios? d) What is

Unformatted text preview: θ tout (angle of transmission out of the last piece of glass) for both scenarios? e) Which scenario will you (the viewer) see a greater amount of vertical displacement? 2. You are taking a picture of a person who is 2m tall, standing 9.2m away from your camera lens which has a focal length f = 0.3m. a) Draw the three principle rays used to locate the image (redraw if necessary). b) Where will the image of the person be located relative to the lens (calculate)? c) What is the transverse magnification of the person (calculate)? d) Is the image inverted or upright? Draw the image....
