A beam of light is incident through the holes on one side of a box emerges out throught holes on its opposite side as shown in the following figure: The box contains:

A beam of light is incident through the holes on side A and emerges out of the holes on the other face of the box as shown in Figure. Which of the following could be inside the box ?

Beams of light are incident through the holes A and B and emerge out of box through the holes C and D respectively as shown in Figure. Which of the following could be inside the box ?

Noor, a young student, was trying to demonstrate some properties of light in her Science project work. She kept ‘X’ inside the box (as shown in the figure) and with the help of a laser pointer made light rays pass through the holes on one side of the box. She had a small butter-paper screen to see the spots of light being cast as they emerged. What could be the ‘X’ that she placed inside the box to make the rays behave as shown?

A light ray is incident at an angle 45∘ on parallel sided glass slab and emerges out grazing the vertical surface. The refractive index of the slab is

Noor, a young student, was trying to demonstrate some properties of light in her Science project work. She kept ‘X’ inside the box (as shown in the figure) and with the help of a laser pointer made light rays pass through the holes on one side of the box. She had a small butter-paper screen to see the spots of light being cast as they emerged. Her friend noted the following observations from this demonstration: i. Glass is optically rarer than air. ii. Air and glass allow light to pass through them with the same velocity. iii. Air is optically rarer than glass. iv. Speed of light through a denser medium is faster than that of a rarer medium. v. The ratio: sin of angle of incidence in the first medium to the ratio of sin of angle of refraction in the second medium, gives the refractive index of the second material with respect to the first one. Which one of the combination of the above statements given below is correct.
