Question
If the temperature of a black body increases from 7oC to 287oC, then the rate of emission of radiation energy is :
Options
A.8 times
B.16 time
C.2 time
D.4 time
Solution
For black body radiation
E = σT4
[E is energy radiated per unit time per unit area, T is termperature of the body]
⇒ E2 = 16 E1
E = σT4
[E is energy radiated per unit time per unit area, T is termperature of the body]
⇒ E2 = 16 E1Create a free account to view solution
