Refraction through a Slab
11
⚡ Quick Summary
When an object is viewed through a transparent slab, its apparent position shifts due to refraction. The shift depends on the slab's thickness and refractive index but is independent of the object's distance from the slab.
Apparent shift = t(1 - 1/μ)
When viewing an object through a transparent slab of thickness 't' and refractive index 'μ', the apparent shift in the object's position is independent of the object's distance 'x' from the slab. The shift is given by t(1 - 1/μ).
Image Formation with a Mirror and Refraction
11
⚡ Quick Summary
When an object at the bottom of a beaker containing water is viewed through a mirror above the water, the position of the final image is affected by both the refraction at the water surface and reflection by the mirror. The apparent depth due to refraction needs to be considered when calculating the image position.

The bottom of the beaker appears to be shifted up by a distance due to refraction. This apparent shift needs to be accounted for when determining the image location after reflection from the mirror.
Refraction through a Slab

⚡ Quick Summary
When light passes through a glass slab, the image of the object is shifted towards the mirror due to refraction at both surfaces of the slab.
Shift = t(1 - 1/μ)
The shift in the position of the image due to refraction through a slab of thickness 't' and refractive index 'μ' is given by a distance t(1 - 1/μ).
