To study refraction of light in rectangular glass slab
1)A ray of light incident on one of the parallel faces of a rectangular glass slab, emerges out of the opposite parallel face
  

2)The path of a ray of light passing through a rectangular slab was traced and angles measured. Which one out of the following is the correct representation of an angle of incidence i, angle of refraction r and angle of emergence e as show in the diagrams
  

 
 
 
 

3)Why does bending of light takes place ? 
  

4)In which direction does a ray bend when it travels from a denser medium to a rarer medium : 
  

5)Refractive index is the property of :
  

6)Does the refractive index of substance change with the colour of light ?
  

7)Give the example of total internal reflection :
  

8)What is critical angle ?
  

9)What is the advantage of "total internal reflection" over reflection ? 
  

10)What do you mean by the statement "Refractive Index of glass is 1.5"
