Question

State whether the given statement is True or False :

One example of resonance involving visible and invisible light in the electromagnetic spectrum is resonance fluorescence.

• A. True
• B. False

Answer 1

The correct option is A True

One example of resonance involving visible and invisible light in the electromagnetic spectrum is resonance fluorescence. Fluorescence itself is a process whereby a material absorbs electromagnetic radiation from one source, then re-emits that radiation on a wavelength longer than that of the illuminating radiation.

Among its many applications are the fluorescent lights found in many homes and public buildings. Sometimes the emitted radiation has the same wavelength as the absorbed radiation, and this is called resonance fluorescence.

Resonance fluorescence is used in laboratories for analyzing phenomena such as the flow of gases in a wind tunnel.
