Looking through a glass Ear will make an object look smaller and slightly lifted. If a slab of glass is placed over a document or piece of paper, then the words will look closer to the surface.
1. Why the words are closer to the surface of glass?
a. Because of the different angle the light is bending.
b. Because of the different angle the light is not bending.
c. Because of the same angle the light is bending.
d. None of these
2. Observe the figure, what is the reason?
a. Due to reflection
b. Due to refraction
3. When a light ray enters a glass slab, it enters from air to glass. Which is the denser medium?
a. Air
b. Glass
4. As light rays travel from rarer to denser medium, the ray of light moves
a. Away from the normal
b. Towards the normal
5. What is the absolute refractive index of glass?
a. 1.3
b. 1.4
c. 1.5
d. 1.6
