- 1. Assume that a camera has a bi-convex lens. Should you move the lens toward or away from the sensor in order to zoom in (magnify)? 2. A camera has a bi-convex lens whose focal length is 50mm. The lens’s range of motion is 5.56mm starting from 50mm from the sensor and moving away. What are the minimum and maximum possible object positions for which the image is in focus? 3. For the camera in the previous question, when a 300mm tall object is at the minimum distance, will it fit on a Canon APS-C sensor? Hint: Look up the size of this camera sensor. 4. See Figure 10.7! A circular piece of glass (n=1.5) has been cut in half as shown and is being used as a lens for a set of five parallel rays. The angles at which the rays are incident on the circular side of the lens are shown, and the image is drawn to scale. First, calculate the 5 angles of refraction for each of the 5 angles of incidence, respectively. Second, use a protractor to draw the refracted rays such that they intersect the…2-Create a ray diagram for eyeglasses that contain a diverging lens.
