Question

Analyzing the spectra of stars, the hottest stars are

• A. red
• B. orange
• C. bluish white
• D. there is no correlation between color and temperature

Answer 1

The correct option is C bluish white

The temperature of the stars are related to their colors by weins displacement law. Larger the temperature, smaller is their wavelength. Thus, of the colors given , red has maximum wavelength and hence smaller temperature, while bluish white has lesser wavelength and highest temperature. Thus, the star that emits bluish-white color has maximum temperature
