Two cancave refracting surfacwe of equal radii fo curvature face each other in air as shown in figure. A point objectO is placed midway between the centreand oneof the poles. Then the separation between the images of O formed by each refracting surface is |

Answer» `11.4` R  `I_(1)` DUETO refraction at surface (1) `(1.5)/(V)-(1)/(R//2)=(1.5-1)/(R)` `(1.5)/(V)=(2)/(R)+(0.5)/(R)` `(1.5)/(V)=(2.5)/(R)` `V=(15)/(R)` `rArr(3)/(5)R=0.6R` `I_(2)` DUE to refraction at surface (2) `(1.5)/(V)=(2)/(-3R//2)-(1.5-1)/(-R)` `(1.5)/(V)=-(2)/(3R)-(0.5)/(R)` `(1.5)/(V)=(-3.5)/(3R)` `V=(+4.5)/(3.5)R` `rArr-(9)/(7)R` `rArr-1.285R`  DISTANCE between `I_(1)&I_(2)=0.114R` |
