Ordinary visible light, including yellow light with a wavelength of 580 nm, does not typically have enough energy to start fires or cause significant heating effects on its own. Visible light is generally considered safe and does not possess the same level of energy as higher-energy forms of radiation like ultraviolet (UV) light or X-rays.
The ability to start a fire or cause heating depends on various factors, including the intensity of the light, the duration of exposure, and the sensitivity of the material to light absorption and heat generation. While visible light can generate some heat when absorbed by objects, it usually does not reach levels sufficient to ignite or cause fires.
However, it's worth noting that certain materials, particularly those that strongly absorb light in the visible spectrum, can be susceptible to heating effects. For example, highly concentrated beams of visible light, such as those produced by lasers, can generate enough heat to ignite flammable materials or cause damage under specific circumstances.
In general, the risk of starting a fire with regular visible light, like yellow light with a wavelength of 580 nm, is low. However, it's always important to exercise caution and adhere to appropriate safety practices when dealing with intense light sources, particularly in situations where flammable materials are present.
