Question

A glass slab is placed over a page on which the word VIBGYOR is printed with each letter in its corresponding colour. 

(i) Will the image of all the letters be in the same place? 

(ii) If not, state which letter will be raised to the maximum. Give a reason for your answer

Answer 1

The image of all the letters of the word VIBGYOR in their corresponding colours will not be at the same place. In glass, red colour has the higher speed than violet colour, so red will be raised to the maximum while violet will be at the bottom and the other colours will be raised in the order I-B-G-Y and orange.
