Question

"In fluorescence microscopy, the wavelength of the emitted light is __________that of the exciting radiation."


Longer than


Shorter than


Equal to


Either longer or shorter than


Impossible to determine

My answer is Longer than am I correct

Answer 1

The emitted wavelength is towards the IR range (from the visible range), relative to the exciting radiation. The difference in wavelength is called the Stoke's shift.
Therefore wavelength of emitted light has a longer wavelength than the exciting radiation.
