Question

A curved surface of radius R separates two medium of refractive indices  and  as shown in figures A and B

Identify the correct statement (s) related to the formation of images of a real object o placed at x from the pole of the concave surface, as shown in figure B

  1. If mu subscript 2 greater than mu subscript 1 , then virtual image is formed for any value of x
  2. If mu subscript 2 less than mu subscript 1 , then virtual image is not formed if calligraphic X less than fraction numerator mu subscript 1 R over denominator mu subscript 1 minus mu subscript 2 end fraction
  3. If mu subscript 2 less than mu subscript 1 , then real image is formed for any value of x
  4. none of these

The correct answer is: If mu subscript 2 greater than mu subscript 1 , then virtual image is formed for any value of x
