The spectra of radiation emitted by two ...

The spectra of radiation emitted by two distant stars are shown below The ratio of the surface temperature of star `A` to that of star `B, T_(A) :T_(B)` is approximately
.

A

`2 :1`

B

`4 :1`

C

`1 :2`

D

`1 :1`

Text Solution

Verified by Experts

The correct Answer is:
A
`lambda_(MA)T_(A)=lambda_(MB)T_(B)("Weins law"),(T_(A))/(T_(B))=(lambda_(MB))/(lambda_(MA))=(1000)/(500)=2:1` .
