58 Physics 51. Light rays from a very small object immersed in water falls on the bubble of radius R. Assume that the object is very close to the surface of the bubble. Refractive index of water is 7 . Take the approximation sine = 0 and cose = 1 where 0 is angle and consider the rays close to a diameter of the bubble. Use the following formula to solve the problem sina sinB siny 2 a b C (see figure) 4 3X 10 2 C b 109 a 9 The image is.....(from the center of the bubble) 30 3 X10 le 2010 R 3 X 106 Object Water 3x1 106 29 1X10 3X (1) Virtual and formed at a distance 3R 2 30 (2) Virtual and formed at a distance 2R 3 90 3R (3) Virtual and formed at a distance 5 3R (4) Real and formed at a distance 2 2016 17)
