C. Producing virtual images The eyepiece of a microscope produces a virtual image to be viewed by the eye, i.e. the rays of light that form the final image diverge from the lens and appear to come from a location behind the eyepiece lens (the image appears to be behind the lens). 1. Make a ray diagram for a converging lens (focal length f) with the object at a distance s < f.

a) Light reflects from the front and back surfaces of a bubble. Assume the bubble is made primarily of water (index of refraction = 1.33). If the bubble has a thickness of 546 nm, what wavelength of light will undergo destructive interference (the bubble will appear dark)? b) An object is 20 cm in front of a diverging lens with a focal length of -6 cm. Calculate the image distance and the magnification. Is the image real or virtual? Upright...

2. Explain why light rays converge when passing through a double convex lens by describing the paths of three light rays; one along the optic axis and the other two parallel to the optic axis. 3. What happens to the image if half a converging lens is covered? Explain why this occurs. 4. What are the conditions necessary to form a virtual image using a converging lens? 5. What type of lens is used in a magnifying glass? Explain how...

(b) Draw the X-ray tube spectrum, i.e., the intensity distribution of X-rays as a function of the frequency of emitted X-ray photons (1) at the exit of the X-ray tube before any filtering takes place, and (2) after the filter but before the X-rays have reached the patient. (c) How does the...
