The temperature of a furnance is 2324^(@...

The temperature of a furnance is `2324^(@)C` and the intensity is maximum in its radiation spectrum at `12xx10^(3)Å`, if the intensity in the spectrum of star is maximum is 4800A, what is the surface tempearture of the star ?

A

`621.95Å`

B

`6219.5^(@)C`

C

`621.95^(@)C`

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B

`lamda_(1)T_(1)=lamda_(2)T_(2)`.
`T_(2)=(lamda_(1)T_(1))/(lamda_(2))`
`rArrT_(2)(12xx10^(3)xx2324)/(4800)=6219.5^(@)C`
Thus correct choice is (b).
