When a piece of metal is heated to high temperatures, it begins to glow red, and then white, as its temperature increases. Does this phenomenon provide
evidence for the wave model or the particle model of light? Why?
A. The wave model, because the wavelengths of emitted radiation
keep changing
O B. The wave model, because the wavelengths of emitted light depend
on the metal's temperature
O C. The particle model, because the metal is emitting packets of light
at specific wavelengths
O D. The pticle model, because the metal is only absorbing radiation
of specific frequencies
