Draw a ray trace diagram showing the image location for a 5 cm tall object placed 8 cm away from a converging lens that has a focal length of 10 cm. is this image real or virtual? upright or inverted? smaller or larger than the original object? 18. a slit of width 0.11 mm is cut in a sheet of metal and illuminated with light from a mercury vapor lamp with a wavelength of 577 nm. a screen is placed 4 meters from the slit. find the width of the central peak in the diffraction pattern in meters on the screen, i. e. find the distance between the first minima on the left and the first minima on the right. 19. it used to be said that the us had spy satellites could read license plates from space. assuming that the altitude of the spy satellite is 200 km above the earth and it needs to be able to resolve points 5 cm apart to read the letters, what should the diameter of the mirror be to achieve this feat? ignore any blurring from the atmosphere and assume diffraction limited optics. 20. suppose than an electron in hydrogen has been excited to the n=3 state. what two wavelength of light would be emitted if the electron fell from the n-3 to n-2 state, then fell from the n=2 down to the ground state? give your answers in nm. is either one of the photons in the visible? which transition if so?
