SUMMARY
The discussion clarifies the relationship between wavelength, energy, and temperature in the context of expanding space. It establishes that as space expands, light's wavelength increases, leading to a decrease in photon energy, as described by the equation E=hf and E=hc/λ. This relationship indicates that longer wavelengths correspond to lower energy and, consequently, lower temperatures. The discussion emphasizes the importance of understanding these quantum mechanics principles for grasping the effects of cosmic expansion on light.
