Number of Images Formed from Reflection & Refraction

[Hydrous Caperilla]

Homework Statement

[/B]
A glass slab of refractive index n=2 has left spherical of radius 10cm and right surface plane.From both surfaces refraction as well as reflection takes place.A point of object P is placed at a distance 15cm from point O1.

Mark the correct option

(A)two images are seen by observed E1
(B)Only one image is seen by observer E2
(C)No images are seen by observed E1
(D)No images are seen by observed E2

Homework Equations

[/B]
None

The Attempt at a Solution

I could think of three cases

(1 ) First the object P will get refracted directly from the left spherical surface .Image no 1
(2) The object P will get reflected from the right surface plane.Image no 2
(3) The object P will get refracted from left spherical surface and then normal plane.Image no 3

So I am getting 3 images which is not in the option.Can anybody tell me what is my mistake

With the geometry you'll have a hard time seeing (3), but yes, in principle it should be there. You can continue that with more reflections, but the intensity will drop quickly and the image will get more and more distorted.

So is my attempt correct

Yes, but I think "two images" is not too wrong as answer.
