The rate of emission of radiation by a body does not depend upon the__________________?
Correct answer: A. Shape and porosity of the body
- A. Shape and porosity of the body
- B. Surface temperature of the body
- C. Nature of the surface
- D. Wavelength of radiation
Explanation
Radiation emission depends on wavelength, surface temperature and surface nature or emissivity. For a given emitting area, it is not fundamentally determined by the body's shape or porosity.
