Figure shows a glowing mercury tube. The intensities at point A, B and C are related as __________ .


  • B > C > A

  • A > C > B

  • B = C > A

  • B = C < A

B = C < A

Here, since B and C have the same distance and lie inclined to make the the same vertical angle with the source, they will have same intensity. But, as A is nearer and forms an angle of 0° with the source, intensity of A will be greater than C or B.
