The sun emits light with a maximum wavelength of 510 nm while another star X emits light of maximum wavelength of 350 nm. What is the ratio of the surface temperatures of the sun and the star ?

0.35

1.5

1.1

0.69

Text Solution

Verified by Experts

The correct Answer is:

`lamda_(m)prop1/T`
`thereforeT_("sun")/T_("star")=(lamda_(m))_("star")/(lamda_(m))_("sun")=350/510=0.69`
