When light is at the red end of the visible spectrum, it has the longest wavelength and the lowest frequency compared to other colors in the spectrum.

1. Wavelength and Frequency: The wavelength of red light is approximately 700 nanometers, and its frequency is about 430 terahertz. This is because, in the visible light spectrum, red light has the longest wavelength and the lowest frequency.

2. Energy: Because energy is inversely proportional to the wavelength, red light has the least energy among the colors in the visible light spectrum.

3. Perception: When this light reaches our eyes, the cones in our retina perceive it as the color red.

4. Heat: Red light is often associated with heat. This is because objects that are heated begin to glow red at lower temperatures than they do for other colors.

5. Infrared Light: Beyond the red end of the visible light spectrum is infrared light, which is not visible to the human eye but can be felt as heat.

So, when light is at the red end of the visible spectrum, it is perceived as red, has the least energy, and is closest to the infrared spectrum.
