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. $\dfrac{{T}_{1}}{{ν}_{1}} = \dfrac{{T}_{2}}{{ν}_{2}} = \dfrac{{T}_{3}}{{ν}_{3}}$
E. The given spectrum could be explained using quantisation of energy
