Physics 9B-C Assignment #4 Cole [34.2] If the tree just fills the mirror, then the top ray and the bottom ray must both hit the eye of the observer. Use the law of reflection for both rays, so the triangle to the tree and the smaller triangle to the eye are similar: h h d d tree mirror tree mirror = õ h h d d tree mirror tree mirror == + = 0 040 28 0 0 350 0 350 324 . .. . . . m mm m m [34.7] 11 1 ss f + = õ 11 175 1 558 10 10 = × s m m õ s' = 1.75 m m s s = = × 314 10 10 11 . . . . m h h i o = õ h i = mh o = ( .)

The radius of curvature of the water surface is on the incident side, so R = - 14 cm. n s n s nn Rs s abb a + = + = = 133 14 0 100 1 133 14 0 14 0 . . . . , cm cm cm and the negative sign means the image is on the incident side, so the fish appears at the center of the bowl. m ns a b = = =+ (. ) ( . ) ( . ) . . 170 100 170 cm cm b) The focal point is where parallel rays of light are focused to a point. The rays of light from an object infinitely far from the surface will be parallel and its image at the focal point. Use s = ∞, and solve for s': n s n s s a + = + = + = 033
