VARIANT 14 1. A clear glass light bulb is placed 1.5 m from a convex lens having a 45 cm focal length. Use ray tracing to get an approximate location for the image. Then use the thin lens equations to calculate (a) the location of the image and (b) its magnification. Verify that ray tracing and the thin lens equations produce consistent results. 2. When driving you need to be able to clearly see road signs and traffic some distance ahead of you as well as the dashboard in your car. Assume that you have a normal lens-to-retina distance. (a) What minimum optical power of the eye is needed to clearly see a road sign 150 m ahead? (b) What maximum optical power is needed to clearly see the dashboard 50 cm away? (c) What range of accommodation AF is needed?

Determine the speed of the electrons incident on the anode surface of the X-ray tube if the minimum wavelength of the emitted X-ray radiation was 5 nm. 4. A 5000-Ci 60Co source used for cancer therapy is considered too weak to be useful when its activity falls 3500 Ci. How long after its manufacture does this happen? The isotope half-life is 5.27 years.
