Refraction in lenses

From the figure shown, establish the relation between μ 1 \mu_1 , μ 2 \mu_2 and μ 3 \mu_3 .

μ 3 > μ 2 ; μ 1 = μ 3 \mu_3 > \mu_2 ; \mu_1 = \mu_3 μ 3 < μ 2 ; μ 1 = μ 3 \mu_3 < \mu_2 ; \mu_1 = \mu_3 None of these μ 3 < μ 2 < μ 1 \mu_3 < \mu_2 < \mu_1

  • Since the ray is parallel as it enters medium 3 (the lense ) therefore refractive index of 1=3.And since the ray converges from 3 to 2 refractive index of 3 <2
