How do we interpret an actual spectrum? • By carefully studying the features in a WebI guess you could think of it as the blackbody feeding all of the energy used for light emission to photons of a certain wavelength. In reality, the blackbody emits light of (almost) all wavelengths, but peaks at a certain wavelength (emits a lot of a certain wavelength at a certain temperature).. So, instead of the emitted light having a range of wavelengths (at … dylan smothers hudlWebDec 29, 2024 · The visible light not absorbed is reflected and makes up the color of the object. If we assume for the sake of argument that objects act close to black bodies and you look at the spectrum emitted by an object around room temperature (we'll take this as 300K), you will see that almost no appreciable amount of energy is in the visible wavelengths. dylan smith south shields

WebApr 10, 2024 · Most objects do not reflect light. They absorb light and re-emit it. When you see regular objects like a house or tree, you are not seeing reflected light. You are seeing light which is emitted by the object. The reason why objects have color is because the objects only emit light in certain frequencies. WebSome objects are so hot they also emit visible light—such as a fire does. Other objects, such as humans, are not as hot and only emit only infrared waves.
