Question

part (c) which temperature most closely corresponds to a star whose spectrum peaks firmly in the ultraviolet region of the spectrum? 7300 k 8600 k 4800 k 4100 k 6000 k 3000 k submit hint 5 submission(s) remaining hints: 0 for a 0% deduction. hints remaining: 0 feedback: 0% deduction per feedback.

Explanation:

Step1: Recall Wien's displacement law

The relationship between the peak - wavelength $\lambda_{max}$ of a black - body spectrum and its temperature $T$ is given by $\lambda_{max}T = 2.898\times10^{-3}\text{ m}\cdot\text{K}$. The ultraviolet region has shorter wavelengths compared to the visible region. Shorter $\lambda_{max}$ corresponds to higher temperatures.

Step2: Compare the given temperatures

We know that higher temperatures will have their spectral peaks in the ultraviolet region. Among the given temperatures $7300\text{ K}$, $8600\text{ K}$, $4800\text{ K}$, $4100\text{ K}$, $6000\text{ K}$, $3000\text{ K}$, the highest temperature is $8600\text{ K}$.

Answer:

$8600\text{ K}$
