Directions : In the following questions, A statement of Assertion (A)...

Speed of light is slower in glass compared to that in air. Hence the refractive index of glass is more than that of air. So the reason is true.

When a double convex air bubble is formed within a glass slab, the refractive index of the medium of the bubble is less than the refractive index of the surrounding medium. Hence the lens will not behave like a converging lens. It will behave like a diverging lens. So, the assertion is false.

Directions : In the following questions, A statement of Assertion (A)...

Assertion: A double convex air bubble is formed within a glass slab. The air bubble behaves like a converging lens.

Reason: Refractive index of glass is more than the refractive index of air.

Explanation:
The given assertion states that a double convex air bubble behaves like a converging lens when formed within a glass slab. The reason provided is that the refractive index of glass is higher than the refractive index of air.

Understanding the Assertion:
To understand the assertion, we need to know the behavior of light when it passes through different mediums with different refractive indices. When light passes from a medium with a lower refractive index to a medium with a higher refractive index, it bends towards the normal. Conversely, when light passes from a medium with a higher refractive index to a medium with a lower refractive index, it bends away from the normal.

Understanding the Reason:
The reason provided states that the refractive index of glass is higher than the refractive index of air. This is a true statement as the refractive index of air is approximately 1, while the refractive index of glass is typically around 1.5. Therefore, the reason is true.

Explanation of the Assertion and Reason:
When light passes through a convex lens, it converges or focuses the light rays. This is due to the shape of the lens and the change in the refractive index of the lens material compared to the surrounding medium. In the case of a double convex air bubble formed within a glass slab, the shape of the bubble acts as a convex lens.

The reason provided supports the assertion. Since the refractive index of glass is higher than that of air, light passing through the glass slab and entering the air bubble will bend towards the normal. This bending of light rays is similar to what happens when light passes through a convex lens.

Therefore, the assertion and reason are both true, and the reason is a correct explanation for the assertion.

Conclusion:
In conclusion, when a double convex air bubble is formed within a glass slab, it behaves like a converging lens. This behavior is due to the difference in refractive indices between glass and air. The refractive index of glass being higher than that of air causes the light rays passing through the glass slab and air bubble to converge, similar to the behavior of a convex lens.

Read the following text and answer the following questions on the basis of the same:Optical Fibre:Optical fibre works on the principle of total internal reflection. Light rays can be used to transmit a huge amount of data, but there is a problem here – the light rays travel in straight lines. So unless we have a long straight wire without any bends at all, harnessing this advantage will be very tedious. Instead, the optical cables are designed such that they bend all the light rays’ inwards (using TIR). Light rays travel continuously, bouncing off the optical fibre walls and transmitting end to end data. It is usually made of plastic or glass.Modes of transmission: Single-mode fibre is used for long-distance transmission, while multi- mode fiber is used for shorter distances. The outer cladding of these fibres needs better protection than metal wires. Although light signals do degrade over progressing distances due to absorption and scattering. Then, optical Regenerator system is necessary to boost the signal.Types of Optical Fibres: The types of optical fibers depend on the refractive index, materials used, and mode of propagation of light. The classification based on the refractive index is as follows: Step Index Fibres: It consists of a core surrounded by the cladding, which has a single uniform index of refraction. Graded Index Fibres: The refractive index of the optical fibre decreases as the radial distance from the fibre axis increases. Q. Light signal through optical fibre may degrade due to

Read the following text and answer the following questions on the basis of the same:Negative Refractive Index: One of the most fundamental phenomena in optics is refraction. When a beam of light crosses the interface between two different materials, its path is altered depending on the difference in the refractive indices of the materials. The greater the difference, the greater the refraction of the beam. For all known naturally occurring materials the refractive index assumes only positive values. But does this have to be the case?In 1967, Soviet physicist Victor Veselago hypothesized that a material with a negative refractive index could exist without violating any of the laws of physics.Veselago predicted that this remarkable material would exhibit a wide variety of new optical phenomena. However, until recently no one had found such a material and Veselago’s ideas had remained untested. Recently, meta-material samples are being tested for negative refractive index. But the experiments show significant losses and this could be an intrinsic property of negativeindex materials.Snell’s law is satisfied for the materials having a negative refractive index, but the direction of the refracted light ray is ‘mirror-imaged’ about the normal to the surface.There will be an interesting difference in image formation if a vessel is filled with “negative water” having refractive index – 1.33 instead of regular water having refractive index 1.33.Say, there is a fish in a vessel filled with negative water. The position of the fish is such that the observer cannot see it due to normal refraction since the refracted ray does not reach to his eye.But due to negative refraction, he will be able to see it since the refracted ray now reaches his eye.Q. A ray incident on normal glass and “negative glass” at an angle 60°. If the magnitude of angle of refraction in normal glass is 45° then, what will be the magnitude of angle of refraction in the “negative glass”?
