Answer:
9660 K
Explanation:
From Wien's Displacement Law, we know that;
Peak wavelength = Wien's Displacement constant/temperature
We are given;
Peak wavelength = 300 nm = 300 × 10^(-9) m
Wien's Displacement constant has a value of 2.898 × 10^(-3) K.m
Thus;
Temperature = (2.898 × 10^(-3))/(300 × 10^(-9)) = 9660 K
