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

The particle model, because the metal is only absorbing radiation

of specific frequencies

Explanation:

The heating of a metal is an example of blackbody radiation. Blackbody radiation refers to the spectrum of light emitted by any heated object; common examples include the heating element of a toaster and the filament of a light bulb. The spectral intensity of blackbody radiation peaks at a frequency that increases with the temperature of the emitting body(Encyclopedia Britianica).

Max Plank proffered explanation to black body radiation by assuming that the oscillators in the heated body emit or absorb energy in discrete frequencies given by E=hf. Hence the energy was directly proportional to the frequency of the oscillator.
