<prompt> Which of the following is true regarding Fluorescence?Spontaneous illumination in darkRelease of longer wavelength light on absorbing light of shorter wavelengthRelease of shorter wavelength light on absorbing light of longer wavelengthContinuous emission of lights of different wavelength  <response>: Ans. b. Release of longer wavelength light on absorbing light of shorter wavelength Ref: Tietz Fundamentals of Clinical Chemistry 5e p75; Lehninger 4447; Harper 29e p311In Fluorescence, there is release of longer wavelength of light on absorbing light of shorter wavelength is seen.FluorescenceIt is the emission of light by a substance that has absorbed light or other electromagnetic radiationQ.It is a form of luminescenceQIn most cases, the emitted lights have a longer wavelength and lower energy than the absorbed radiationQ.
