Vedclass · Answer

(C) $Cathode$ $ray$ $oscilloscope$ $(CRO)$ uses an electron beam generated by an electron gun. These high-speed electrons are directed towards a screen coated with a fluorescent material (like zinc sulfide). When the electrons strike the fluorescent screen,they transfer their kinetic energy to the atoms of the material,causing them to emit light,which is known as fluorescence. Therefore,the correct device is the $Cathode$ $ray$ $oscilloscope$.

Which one of the following devices makes use of the electrons to strike certain substances to produce fluorescence?
