When cool, dense objects become very hot, their blackbody radiation changes in that
It becomes brighter
Its brightness peaks at shorter wavelengths
It changes color
All of the above
A.It becomes brighter
B.Its brightness peaks at shorter wavelengths
C.It changes color
D.All of the above
Explanation / Answer
1. both B and C
2
All of the above'
since L*T = constant = 0.0029
also I = AE sigma T^4
when body heats, its temperature increases, so it becomes brigther
the as LT is cosntant, L decrases, wavelgnth becomes shorter,
thus colour also changes
