The temperature of filament of bulb is 5...

The temperature of filament of bulb is 500 K and amount of heat radiated is E the filament is supposed to be a black body, the amount of heat radiated when the temperature of filament is 1000 K is :

A

16 E

B

2 E

C

4 E

D

8 E

Text Solution

Verified by Experts

The correct Answer is:
A
`(E_(2))/(E_(1))=((T_(2))/(T_(1)))^(4)`
`E_(2)=E((1000)/(500))^(2)" "E_(2)=16E`
Thus correct choice is (a).
