The wavelength of the radiation emitted by the star is 183 nm.
Explanation:
As per Wien's displacement law, the product of emitted wavelength and temperature of the star will be equal to 2.898 × 10⁻³ mK.
So if the wavelength of the emitted radiation by Sun is given as 550 nm, then the temperature of the Sun will be
Then if the temperature of star is said to be 3.5 times hotter than Sun, then the temperature of Star = 3.5×5.27×10³ = 15.81×10³ K.
With this temperature, the wavelength of the emitted radiation can be found as follows:
So, the wavelength of the radiation emitted by the star is 183 nm.
