1. Consider a convex lens with a focal length of 5.50 cm. Anobject is located at 13.50 cm. The object is 6.00 cm tall. Draw theray diagram to scale. Determine the image distance, the height ofthe image, the magnification and the characteristices of the image.Pay attention to the sign conventions and units.
2. White light shines through a diffraction grating with 7300lines per cm. Make a table of diffraction angles for m = 1, 2, 3,... versus the wavelengths of red and blue light. Stop when theangle is undefined. Note there may be more starts than finishes.Based on your table: How many complete diffraction patterns arethere? What is the wavelength of the light diffracted at 90 degreesfor the highest order incomplete diffraction pattern? Remember thatthe wavelength range of visible light is from 400 nm (blue) to 700nm (red).
