As a Newly Formed Star Continues to Contract, Its Temperature

question 124

Multiple Choice

As a newly formed star continues to contract, its temperature increases, while the chemical nature of the gas does not change. Which of these could happen to the peak wavelength of its emitted radiation?

• A) The peak wavelength will move toward shorter wavelengths (e.g., IR to visible).
• B) The peak wavelength will not change because it does not depend on temperature.
• C) The peak wavelength will remain constant because the chemical state of the gas does not change.
• D) The peak wavelength will move toward longer wavelengths (e.g., visible to IR).
