Magnetic screening around the tube of a cathode ray oscilloscope (CRO) is essential because external magnetic fields can distort the electron beam, leading to inaccurate readings and image instability. By shielding the tube from these fields, the oscilloscope can maintain precise control over the electron paths, ensuring clear and accurate waveform displays. This enhancement in performance is crucial for reliable measurements in various applications.

to get high acceleration for the beam.
It works on the following principles : (i)thermionic emission (ii)deflection of the electron beam by the electric and magnetic field (iii)fluorescence produced by the electron beam on a fluorescent screen
A: xray emits from TV, OSCILLOSCOPE and some more instruments due to requirement of hi voltage to see the display
To connect a cathode ray oscilloscope (CRO) to a full-wave rectifier, first, ensure the rectifier circuit is powered and functioning properly. Connect the oscilloscope probes across the output terminals of the rectifier; the positive probe should connect to the positive output, and the ground clip to the common ground. Set the oscilloscope to an appropriate voltage scale and time base to visualize the rectified waveform. Finally, observe the display, which should show the full-wave rectified signal.

In a cathode ray oscilloscope (CRO), the anode serves to accelerate the electrons emitted by the cathode towards the screen at the other end of the tube. This acceleration helps to produce a focused beam of electrons which can then be deflected by the electric or magnetic fields to create an image on the screen.
Cathode rays are negatively charged particles that move in curved paths in the presence of a magnetic field. The direction and curvature of the cathode rays can be controlled by adjusting the strength and orientation of the magnetic field. This phenomenon is known as the magnetic deflection of cathode rays and is used in devices like cathode ray tubes.
