States Of Matter Question 1
Question 1 - 24 January - Shift 2
Following figure shows spectrum of an ideal black body at four different temperatures. The number of correct statement/s from the following is
Wavelength
A. $T_4>T_3>T_2>T_1$
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. $\frac{T_1}{V_1}=\frac{T_2}{V_2}=\frac{T_3}{V_3} \neq$ constant
E. The given spectrum could be explained using quantisation of energy.
Show Answer
Answer: (2)
Solution:
Formula: Quantization of Energy
The spectrum of Black body radiation is explained using quantization of energy. With increase in temperature, peak of spectrum shifts to shorter wavelength or higher frequency. For above graph $\to T_1>T_2>T_3>T_4$.
