O1.0 mm di question4 1 pts the light spectrum of a star shows the peak wavelength emitted by thel star to be at 400 nm. what is the surface temperature of the star? 9875 k o 4625 k 7250 k 8750 k

the surface temperature of star is 7250 K

Explanation:

Given data

wavelength = 400 nm

to find out

the surface temperature of star

solution

we will apply here wiens law formula that is given below

wavelength × temperature  = 0.0029 m-k    1

put the value of wavelength in equation 1 so we get temperature here

wavelength × temperature  = 2900000 nm-k  

temperature = 2900000 / 400

temperature = 7250 K

so the surface temperature of star is 7250 K
