(1) Use your measured minimum deviation angle, d min , the geometric relationships on page 4-4 of the Lab Manual, and Snell's Law to calculate the index of refraction of your prism. (2) Determine the critical angle as found on the computer. Calculate the critical angle based on the index of refraction from (1), and compare the two. (3) Compare the measured focal lengths of your lenses with that predicted by the "lens- maker's equation" (Tipler eq. 31-18): 1/f = (n-1) (1/r 1 - 1/r 2 ). (4) Using your convex lens, investigate what happens to the focal length as you change

Unformatted text preview: the thickness of the lens (leaving all other parameters the same). Describe briefly. (5) (6) (7) (8) Lens equation (Tipler 31-19): 1/s + 1/s' = 1/f. Sign conventions: s, the distance of the object from the lens, is positive on the incident side (real object). s', the image distance, is positive on the transmission side (real image) and negative on the incident side (virtual object). f is positive for converging lenses, negative for diverging lenses. Linear magnification: m = y'/y = -s'/s. A negative magnification means the image is inverted....
