Final answer:
As the wavelength of light increases, its frequency decreases, leading to a decrease in energy according to the equation E = hf. Additionally, higher temperatures result in emissions of light at shorter wavelengths, indicating higher energy levels.
Step-by-step explanation:
The amount of energy in light changes as the wavelength increases. According to the relationship given by the equation c = λf where c is the speed of light, λ is the wavelength, and f is the frequency, we see that frequency and wavelength are inversely related. Since the speed of light is constant, an increase in wavelength results in a lower frequency. Considering the energy of a photon is given by the equation E = hf, where h is Planck's constant and f is the frequency, it becomes clear that as wavelength increases, the frequency and thus the energy of light decreases.
Another key observation is that temperature affects the energy distribution of the emitted light. As the temperature of an object increases, it emits more radiation at shorter wavelengths which correspond to higher energy. This is demonstrated by the fact that higher temperatures lead to the visible emission of light that shifts from the red to blue end of the spectrum, indicating an increase in energy.
