I am not getting the same answer from the experts for this question that I asked...... One had said that the base will not appear to rise when seen vertically..... And this one said it will rise.......
I'm confused. So someone plz clear my doubt regarding this ques......

Subject: Physics, asked on 2/8/19

If we see the base of container vertically , will there be the same rise in the depth of the base or there won't be any rise in the apparent depth when seen vertically above?????
Plz explain with a diagram showing a ray vertically for the same....

Will the height of the base of the container appear to rise due to refraction even if it is seen from the normal position ,vertically above????
Plz answer with a diagram of a container filled with water when viewed from vertically above..

Subject: Physics, asked on 28/7/19

Does this phenomenon in the diagram mean that we will see the SAME lateral shift or rise of the depth of the base when we see the base from any position or angle from the surface?????
OR will the rise in height CHANGE for every position i.e. different heights are observed at different positions??????

Please solve this

24. Figure shows two unmixable transparent liquids of refractive indices μ1 and μ2 filled in a container. The depth of each liquid is d. Calculate apparent depth of a coin placed at bottom of container.
 
Apparent depth=d1μ1+1μ2

The images are formed after reflection from both the surfaces, except for the first image. The second image is the brightest of all as minimum absorption takes place and it bounces of the silvery layers which makes the bottom surface
