17. Draw a ray trace diagram showing the image location for a 5cm tall object placed 8 cm away from a converging lens that has afocal length of 10 cm. Is this image real or virtual? Upright orinverted? Smaller or larger than the original object?
18. A slit of width 0.11 mm is cut in a sheet of metal andilluminated with light from a mercury vapor lamp with a wavelengthof 577 nm. A screen is placed 4 meters from the slit. Find thewidth of the central peak in the diffraction pattern in meters onthe screen, i.e. find the distance between the first minima on theleft and the first minima on the right.
