Imagine an electric stove where a setting of 6 heats the coil, but it still appears black. when the dial is turned to 7, the coil begins to noticeably glow red, which means that the power density of the radiation at 700 nm (visibly red) surpassed a threshold. at what approximate temperature is the coil when it begins to glow red? assume the human eye can only perceive a glow when the power density of light reaches a minimum of 10 w/m2/μm (where y-axis units appear in the simulation in terms of megawatts (mw/m2/μ
express the temperature in degrees celsius to two significant figures.
