Question
Three bodies A, B and C have equal surface area and thermal emissivities in the ratio eA : eB : eC = 1 : 
All the three bodies are radiating at sme rate. Their wavelengths corresponding to maximum intensity are λA, λB, and λC respectively and tempratures are TA,TB and TC on kelvin scale, then select the incorrect statement :-
All the three bodies are radiating at sme rate. Their wavelengths corresponding to maximum intensity are λA, λB, and λC respectively and tempratures are TA,TB and TC on kelvin scale, then select the incorrect statement :-Options
A.
= TB
= TBB.
= λB
= λBC.
= eBTB
= eBTBD.
= eCλCTC
= eCλCTCSolution
For same power of radiation
PA = PB = PC ⇒ eAσATA4 = eBσATB4 = eAσATA4 = eCσATC4
& λATA = γBTB = λCTC(eA : eB : eC = 1 :)
⇒ = TB or = eBTB & =
