The figure shows three transparent media of refractive indices \(\mu_1,~\mu_2\) and \(\mu_3\). A point object \(O\) is placed in the medium \(\mu_2\). If the entire medium on the right of the spherical surface has refractive index \(\mu_1\), the image forms at \(O'.\) If this entire medium has refractive index \(\mu_3\), the image forms at \(O''.\) In the situation shown,

                

1. the image forms between \(O'\) and \(O''.\)
2. the image forms to the left of \(O'.\)
3. the image forms to the right of \(O''.\)
4. two images form, one at \(O'\) and the other at \(O''.\)

Consider three converging lenses \(L_1,\) \(L_2\) and \(L_3\) having identical geometrical construction. The index of refraction of \(L_1\) and \(L_2\) are \(\mu\)1 and \(\mu\)2 respectively. The upper half of the lens \(L_3\) has a refractive index \(\mu\)1 and the lowest half has \(\mu\)2 (figure). A point object \(O\) is imaged at \(O_1\) by the lens \(L_1\) and at \(O_2\) by the lens \(L_2\) placed in same position. If \(L_3\) is placed at the same place,

      

a. there will be an image at \(O_1\)
b. there will be an image at \(O_2\)
c. the only image will form somewhere between \(O_1\) and \(O_2\)
d. the only image will form away from \(O_2\)

Choose the correct option:
1. (a) and (b)
2. (b) and (c)
3. (c) and (d)
4. all of these
