Three discs A, B and C having radii 2, 4, and 6 cm respectively are coated with carbon black. Wavelength for maximum intensity for the three discs are 300, 400 and 500 nm respectively. If QA, QB and QC are power emitted by A, B and D respectively, then
  • a)
    QA will be maximum
  • b)
    QB will be maximum
  • c)
    QC will be maximum
  • d)
    QA = QB = QC
Correct answer is option 'B'. Can you explain this answer?
