Ultraviolet catastrophe:
A shortcoming of the Rayleigh-Jeans formula, that tries to explain the radiancy of a blackbody at several frequencies of the electromagnetic spectrum. It was obviously wrong since as the frequency enhanced, the radiancy enhanced without bound; something quite not observed; it was dubbed the "ultraviolet catastrophe." It was later on reconciled and described by introduction of the Planck radiation law.
Q. When the negative feedback is practical to an amplifier of gain 50 the gain falls to 25. Compute the feedback ratio? Af = A / 1 + Aβ 25 = 50 / 1 + 50 β 1 = 2 / 1 + 50
