Question

The image of point P when viewed from top of the slabs will be

  1. 2.0 cm above P    
  2. 1.5 cm above P    
  3. 2.0 cm below P    
  4. 1 cm above P    

The correct answer is: 1 cm above P


    The two slabs will shift the image a distance
    d equals 2 open parentheses 1 minus fraction numerator 1 over denominator mu end fraction close parentheses t equals 2 open parentheses 1 minus fraction numerator 1 over denominator 1.5 end fraction close parentheses open parentheses 1.5 close parentheses equals 1 c m
    Therefore, final image will be 1 cm above point P.
