Question

compared with the peak wavelength given off by the sun, what is the peak wavelength given off by a hotter star? shorter in wavelength and higher in energy shorter in wavelength and lower in energy longer in wavelength and higher in energy longer in wavelength and lower in energy

Explanation:

According to Wien's displacement law, the peak - wavelength of a black - body radiation is inversely proportional to its temperature. A hotter star has a higher temperature. So, it has a shorter peak - wavelength. Also, from the energy - wavelength relation $E=\frac{hc}{\lambda}$ (where $E$ is energy, $h$ is Planck's constant, $c$ is the speed of light, and $\lambda$ is wavelength), a shorter wavelength means higher energy.

Answer:

shorter in wavelength and higher in energy
