Name the three types of spectacular explain briefly the cause of this spectra

1 answer

1. Continuous spectrum - This type of spectrum is produced when an object emits light at all wavelengths. The continuous spectrum is created by hot, dense objects such as the sun or a light bulb, where atoms are tightly packed and emit a continuous range of wavelengths.

2. Emission line spectrum - This type of spectrum is produced when an object emits light at specific wavelengths, producing bright lines or bands. Emission line spectra are created when atoms in a hot, low-density gas become excited and emit photons at specific wavelengths as they return to their ground state.

3. Absorption line spectrum - This type of spectrum is produced when light passes through a cool, low-density gas and certain wavelengths are absorbed by the atoms in the gas, creating dark lines or bands in the spectrum. Absorption line spectra occur when atoms in a cool, low-density gas absorb photons at specific wavelengths, causing the dark lines in the spectrum.
