The three types of spectra
WebThe electromagnetic spectrum, in simple terms, is defined as the range of all types of electromagnetic radiation. We shall learn about the concept in detail and understand all its underlying aspects in this lesson. What Is the … WebThe three main types of spectra: continuous, absorption, emission. Different spectral types. NOAO/AURA/NSF. Spectral Type. A star is a hot dense ball of gas so we should expect it have a continuous spectrum. But stars also have thin, transparent outer layers that light has to pass through.

WebLight which passes through a spectroscope produces 3 types of spectra: Continuous (rainbow) spectrum—produced by a hot, dense object. A continuous spectrum is also called blackbody radiation. Emission spectrum—produced by a hot, rarefied gas … WebJan 29, 2024 · Most light sources can be classified into three main types: continuous, absorption, and emission. A hot, opaque object, like the filament in an incandescent light bulb, emits a continuous spectrum, having light of all wavelengths. A hot, dense gas is another example of an object that emits a continuous spectrum.
