SSC MTS EXAM

Detailed explanation-1: -Black-body radiation has a characteristic, continuous frequency spectrum that depends only on the body’s temperature, called the Planck spectrum or Planck’s law.

Detailed explanation-2: -A black body emits radiations of maximum intensity at a wavelength of 5000 Å, when the temperature of the body is 1227o C. If the temperature of the body is increased by 1000o C, the maximum intensity of emitted radiation would be observed at. No worries!

Detailed explanation-3: -A black body also is a perfect emitter of light over all wavelengths, but there is one wavelength at which its emission of radiation has its maximum intensity. Hotter objects emit more radiation than colder objects over all wavelengths.
