The plots of intensity against wavelength for three black bodies at temperatures T₁ , T₂ and T₃ are as shown. The wavelengths are such that

Step-by-step solution

From the given graph, the horizontal axis represents the wavelength . Let ₁ , ₂ , and ₃ be the wavelengths corresponding to the maximum intensity (the peaks of the curves) for the black bodies at temperatures T₁ , T₂ , and T₃ respectively. By observing the positions of the peaks along the -axis: The peak of the curve for T₁ is furthest to the left, meaning it corresponds to the smallest wavelength, so ₁ is the minimum. The peak of the curve for T₃ is in the middle, so ₃ is greater than ₁ . The peak of the curve for
