Light Reflectio...

A light ray passes from a material of low refractive index to one of high refractive index. Which of the pairs of quantities listed below describes the light ray as it strikes and passes through the interface between the two materials? Match the descriptions below with the statement that best describes the situation.
Statement: A part of the light ray remains inside the low refractive index material.

A ray of light incident on the interface of the medium $$A$$ and $$B$$ and it passes through medium $$B$$ as shown in above figure. Choose the correct option.

A beam of light passing from air enters into the glass. Identify which of the following statements is true?

Choose the correct option which is true about a bi-concave lens :

A converging lens has formed an image at a distance of 60 cm from the lens and the height of the image is $$\frac{1}{4}$$ the height of the object. Calculate the focal length of the lens. 

A ray of light incident on a piece of glass as shown above. The light passes through the glass and emerged into the air. A, B, C, D and E are possible paths of light. Choose the best possible path of light.

The image of a person appears inverted on the far side of an optical instrument . Identify the optical instrument?

In your laboratory, you trace the path of light rays through a glass slab for different values of angle of incidence $$(\angle i)$$ and in each case, measure the values of the corresponding angle of refraction $$(\angle r)$$ and angle of emergence$$(\angle e)$$. Based on your observations, the correct conclusion is

Study the following four experimental set-ups I, II, III and IV for the experiment, "To trace the path of a ray of light through a rectangular glass slab."
Which of the marked set-ups is likely to give best results (P1 and P2 are the positions of pins fixed on the incident ray) ?

On the basis of their experiment, "To trace the path of a ray of light through a rectangular glass slab," students of a class arrived at which one of the following conclusions :
