State:
(a) The S.I. unit of the intensity of a blackbody radiation.
(b) Two features of the intensity-wavelength graph of a perfect blackbody at different temperatures.
Verified Correct Answer: .
Physical Principles & Numerical Solution
(a) S.l unite for the intensity of a blackbody radiation = Wm-² OR Js\(^{-1}\)m-²
(b) Two features of the graph
i. The shape of the graph is non-symmetric.
ii. Peaks of the intensity have lower wavelengths/Peaks decrease with wavelength.
iii. The line joining the peaks have a negative gradient.
