Answer 2

Answer:

The CRO recruit the cathode ray tube and act as a heat of the oscilloscope. In an oscilloscope, the CRT produces electron beam which is accelerated to high velocity and brings to the focal point on a fluorescent screen. Thus, the screen produces a visible spot where the electron beam strikes with it.
