A ceramic sample is taken out of a furnace and left to cool in a laboratory. A spectrometer records how the intensity of the radiation emitted by the sample is spread across a range of wavelengths.
Which change is seen in the recorded distribution as the sample cools?
The peak stays the same height and moves to a longer wavelength.
The peak becomes lower but stays at the same wavelength.
The peak becomes lower and moves to a shorter wavelength.
The peak becomes lower and moves to a longer wavelength.
