Pick out the correct statement.
(A) Higher is the temperature of the radiating body, higher is the wavelength
of radiation
(B) Logarithmic mean area is used for calculating the heat flow rate through
a thick walled cylinder
(C) The wavelength corresponding to maximum mono-chromatic emissive
power increases with rise in temperature
(D) Solid angle subtended by the finite surface at the radiating element is
called the angle of incidence
