What changes should an observer expect to see in the resulting spectrum of emitted light from a piece of metal when it is heated slowly in an intense flame from 500 K to 1500 K?
A) The intensity of radiation would increase greatly, while the color would change from blue through white to red.
B) The intensity of radiation would increase greatly, and the color would change from red through white to blue.
C) The intensity of radiation would increase greatly, while the color would remain a dull red.
D) The intensity of radiation would increase only slightly, while the color would change from red through white to blue.

Question

Quizplus · Accepted Answer

As a piece of metal is heated, it emits more radiation due to increased energy, and the peak wavelength of emitted light shifts to shorter wavelengths. This shift follows Wien's displacement law, moving from red (lower temperature) through white (medium temperature) to blue (higher temperature), indicating an increase in temperature from 500 K to 1500 K.
