An astronomer monitors a distant carbonaceous asteroid as it recedes from its parent star. Over several months, the average temperature of the asteroid is observed to steadily decrease.
Which statement correctly describes the change in the peak wavelength of the asteroid's emitted electromagnetic radiation, and the balance of radiation power, during this cooling process?
The peak wavelength of the emitted electromagnetic radiation decreases, and the rate of radiation absorbed is greater than the rate of radiation emitted.
The peak wavelength of the emitted electromagnetic radiation increases, and the rate of radiation absorbed is less than the rate of radiation emitted.
The peak wavelength of the emitted electromagnetic radiation decreases, and the rate of radiation absorbed is less than the rate of radiation emitted.
The peak wavelength of the emitted electromagnetic radiation increases, and the rate of radiation absorbed is greater than the rate of radiation emitted.
