Explanation:
It is given that peak (maximum) emission of star is 300 nm.
And, it is known that according to Wein's displacement relation between wavelength and temperature is as follows.
[tex]\lambda_{max} \times T[/tex] = 2898 micrometer.K
Hence, putting the given values into the above formula as follows.
[tex]\lambda_{max} \times T[/tex] = 2898 micrometer.K
[tex]300 \times 10^{-9} m \times T[/tex] = 2898 \times 10^{-6} meter.K
T = [tex]\frac{2898000}{300}[/tex] K
= 9660 K
Thus, we can conclude that the estimated surface temperature of star is 9660 K.
