Respuesta :
As per Weins displacement law the wavelength of light for which we get the peak of the graph is always inversely proportional to the temperature.
So we can say
[tex]/lambda = \frac{b}{T}[/tex]
So here if temperature becomes more cool then wavelength will increase
here we know that
[tex]\lambda_1 = 8500 A^o[/tex]
[tex]\lambda_2 = 6000 A^o[/tex]
[tex]\lambda_3 = 3500 A^o[/tex]
It means the hottest star out of all three is star 3
and coolest star is star 1
now if we star 2 becomes cooler then it means its temperature will go near to star 1 and hence it will more look like to star 1.
So correct answer is
it will look more like Star 1
