If temperature becomes double, the emitted radiation will be :

A

16 times

B

8 times

C

`2sqrt(2)` times

D

32 times

Text Solution

Verified by Experts

The correct Answer is:
A
From stefan's law
`:. (E_(1))/(E_(2)) =((T_(1))/(T_(2)))^(4)`.....(i)
here `E_(1)=E` (Initial radiation say)
`T_(1)=T, T_(2)=2T`
`:. (E_(1))/(E_(2))=(T/(2T))^(4)`
`rArrE_(2)=16E`
