∴ Thickness of the slab = R1 + R2
= 7.5 + 3 = 10.5 cm
= 7.5 + 3 = 10.5 cm

Also known as a lens) will behave differently depending on its position within the slab.
If the air bubble is in the middle of the slab, it will act as a diverging lens. This means that it will cause light rays passing through it to spread out, or diverge. This can be observed by looking through the slab and seeing objects appear smaller and farther away than they actually are.
On the other hand, if the air bubble is closer to one of the surfaces of the slab, it will act as a converging lens. This means that it will cause light rays passing through it to come together, or converge. This can be observed by looking through the slab and seeing objects appear larger and closer than they actually are.
The behavior of the air bubble as a lens is due to the difference in refractive index between the air inside the bubble and the glass slab. The refractive index is a measure of how much light is bent or refracted when it passes through a material. In the case of the air bubble, the difference in refractive index between the air and the glass causes the light rays passing through the bubble to bend, resulting in the lens-like behavior.
It is worth noting that the effect of the air bubble as a lens may be more pronounced if the slab is made of a material with a higher refractive index, such as glass or plastic. Additionally, the size and shape of the air bubble can also affect its lens-like behavior.
