Question

. On heating, the amplitude of vibration of the atoms or molecules of an object

Answer 1

Answer:

Here is the answer....

Frequency is determined by the rate of the electron as it orbits the nucleus. This is why different substances reflect different frequencies of light, since their orbitals are different sizes. Likewise, amplitude is determined by the energy of the electron in its orbital path. This is why an object becomes red hot before it becomes white hot, since red is a lower frequency of light which represents an electron orbiting a nucleus more slowly and therefore emitting a lower frequency of electromagnetic radiation. Then it becomes white hot as it gets hotter because White White is a combination of red with higher frequencies of light, which are generated as electrons move faster. Then the white gets brighter as the amplitude increases. This is how light bulbs work. It is also why light bulbs use a carbon filament, because carbon is the most electrically stable element at higher temperatures because it has the most open orbitals.
