Final answer:
Hotter objects emit more total energy than cooler objects, and the hotter the emitting body, the shorter the wavelength at which the maximum power is emitted.
Step-by-step explanation:
The hotter an object is, the more total energy it emits compared to cooler objects. This is because objects at higher temperatures have more collisions between atoms and therefore give off more energy. In stars, hotter stars emit more energy at every wavelength compared to cooler stars. Additionally, the graph shows that at higher temperatures, the wavelength at which the maximum power is emitted becomes shorter. A shorter wavelength corresponds to a higher frequency and energy. This means that hot objects emit a larger fraction of their energy at shorter wavelengths compared to cool objects. For example, an electric stove burner emits infrared radiation (heat) at a low temperature, but starts to emit visible light at higher temperatures. Mathematically, the energy flux emitted by a blackbody at temperature T is proportional to the fourth power of its absolute temperature, which is known as the Stefan-Boltzmann law.
