Question

what is fluorescence

Answer 1

Hey mate here is your answer:-

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation .It is a form of luminescence.In most case, the emitted light has longer wavelength, and therefore lower energy, then the absorbed radiation.

Answer 2

Fluorescence is the property if the molecule emits light at a specific wavelength when it is irradiated by light of a shorter wavelength that is Electromagnetic radiation at one wavelength is absorbed and is then re-emitted at a longer wavelength.

Explanation:

• It is the emission of electromagnetic radiation which is caused by the excitation of atoms in a material.

• Those substances on which when radiation is incident, they also start radiating light are known as fluorescence.

• These are spontaneous reaction because as soon the light is incident the substance starts radiating light.

• The emission of radiation stops as soon as the incident radiation is stopped.

• In a short duration, the electron moves from the excited singlet state to the ground state.

• For fluorescence to occur ultraviolet or visible radiations are required.

• No change in property occurs in this phenomenon.
