Question

Following figure shows spectrum of an ideal body at four different temperature. The number of correct statement/s from the following is _________. Wavelength Energy Distribution T1 T2 T3 T4 A. T4 > T3 > T2 > T1 B. The black body consists of particles performing simple harmonic motion. C. The peak of the spectrum shifts to shorter wavelength as temperature increases. D. 1 v T = 2 v T = 3 v T constant E. The given spectrum could be explained using quantisation of energy.

Correct answer: .. (A) Wavelength Energy Distribution T1 T2 T1 > T2> T3>T4 T3 T4 Wavelength of radiation emitted by black body decreases with increase in temperature. (C) The peak of spectrum shift to shorter wavelength as temperature increases. (E) Given spectrum could be explained by quantization.
