Unformatted text preview: n w ( R/ 2) + 1 s = (1-n w )-R 1 s = ( n w-1) R-2 n w R =-(1 + n w ) R ⇒ s =-3 7 R. The image from above is virtual and is formed in the water, (3 / 7) R below the surface. (b) Using the same equation, we can ﬁrst ﬁnd the image formed by refraction at the water-glass interface. Taking R = ∞ for the ﬂat interface yields, n w ( R/ 2) + n g s = 0 ⇒ s =-n g 2 n w R =-5 8 R. This image is within the water, (5 / 8) R from the water-glass interface. It serves as the object for the image formed by refraction at the glass-air inter-face. The distance to that interface is (5 / 8) R + R = (13 / 8) R : n g (13 / 8) R + 1 s = 0 ⇒ s =-(13 / 8) n g R =-39 40 R. The image seen from below the glass is within the glass, (39 / 40) R from the glass-air interface....
