Two glass hem heres of refractive index and radius R are placed with their plane surfaces opposed separated by a distance d Answer A B C D Your Attempt Correct answer Rate this question If the combination is achromatic for rays parallel to the axis when their planes surfaces are facing towards each other then the value of d R 1 If the combination is achromatic for rays parallel to the axis when their planes surfaces are 2R facing towards each other then the value of d 1 If the combination is achromatic for rays parallel to the axis when their curved surfaces are R facing towards each other then the value of d 1 If the combination is achromatic for rays parallel to the axis when their curved surfaces are facing towards each other then the value of d R 2 1 1
