A ) the surface temperature of red star is about 4500 K
B ) the surface temperature of yellow star is about 5100 K
C ) the surface temperature of blue star is about 6200 K
D ) the surface temperature of white star is about 5600 K
<h3>Further explanation</h3>
Let's recall the Wien's Displacement Law as follows:
where:
<em>λ_max = the wavelength of the maximum radiation energy ( m )</em>
<em>T = surface temperature of the star ( K )</em>
Let us now tackle the problem!
<u>Given:</u>
wavelength of red light = λ_r = 650 nm = 650 × 10⁻⁹ m
wavelength of yellow light = λ_y = 570 nm = 570 × 10⁻⁹ m
wavelength of blue light = λ_b = 470 nm = 470 × 10⁻⁹ m
wavelength of white light = λ_w = 520 nm = 520 × 10⁻⁹ m
