Kirchoff‟s law applies to _____________ radiation?
Correct answer: C. Both A. & B.
- A. Total
- B. Monochromatic
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
Kirchhoff’s radiation law relates emissive power and absorptivity for both total radiation and radiation at a specified wavelength, called monochromatic radiation. Hence both categories are covered.
