1. Consider a convex lens with a focal length of 5.50 cm. An object is located at 13.50 cm. The object is 6.00 cm tall. Draw the ray diagram to scale. Determine the image distance, the height of the 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 7300 lines per cm. Make a table of diffraction angles for m = 1, 2, 3, ... versus the wavelengths of red and blue light. Stop when the angle is undefined. Note there may be more starts than finishes. Based on your table: How many complete diffraction patterns are there? What is the wavelength of the light diffracted at 90 degrees for the highest order incomplete diffraction pattern? Remember that the wavelength range of visible light is from 400 nm (blue) to 700 nm (red).
