Why the speed of electron beam is greater than the light speed in cathode ray oscilloscope?
Why is the speed of the electron beam greater than the speed of light in cathode ray oscilloscope.
How a Cathode Ray Oscilloscope is used to measure Period?
period are measued in oscilloscope by using or calculating time division
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
What prompted early scientists to propose that the ray of the cathode ray tube was due to the cathode?
The electron had already been discovered. It took little imagination to "see" that the cathode ray was the beam of electrons that originated from the cathode. And the beam was controlled using techniques based directly on what was correctly understood about the electron. The cathode ray could only be an electron beam generated at the cathode. Conventional elctric current flow is usually thought of as flowing from positive to negative, but at the quantum level; due to electrons having a negative charge; technically they really flow from negative to positive, and this is apparent in the cathode ray tube. Its the negatively charged electrons that glow in a cathode ray tube, and do so from the negative terminal, or cathode, hence the name.
Does a cathode ray produce red fluorescence?
The cathode ray is just a beam of electrons. The color of the fluorescence depends on the substance in the target.
What is the deflection sensitivity of a cathode ray oscilloscope?
It is the deflection on the screen (meter) per volt of deflection
What is the unit of deflection sensitivity of cro?
The unit of deflection sensitivity of a Cathode Ray Oscilloscope (CRO) is volts per division on the vertical axis of the screen. It represents how much voltage change is needed to move the electron beam by one division vertically on the screen.
What is horizontal and vertical amplifier in cathode ray oscilloscope?
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.
How does the anode voltage applied to the cathode ray oscilloscope affects the sensitivity of the CRO?
The anode voltage does not affect the sensitivity of a CRO. The input amplifier and deflection circuit have a greater influence. The Anode voltage will affect the focus and visibility of the trace, in this respect it will affect how you see the result.
What is magnetic deflection senstivity?
Magnetic deflection sensitivity of a cathode ray oscilloscope (CRO) is defined as the amount of deflection of electron spot produced when a magnetic flux density of 1 Wb/m2 is applied. SM = (e / m )1\2 x 1\ (2V0) 1\2 x l x L
How does the position of the plates affect the sensitivity of the Cahtode Ray Oscilloscope?
The position of the plates in a Cathode Ray Oscilloscope (CRO) affects sensitivity by altering the electric field that influences the electron beam's trajectory. When the plates are closer together, the electric field strength increases, allowing for a more pronounced deflection of the beam for a given voltage, which enhances sensitivity. Conversely, if the plates are positioned farther apart, the electric field is weaker, resulting in less deflection and reduced sensitivity. Adjusting the plate position helps optimize the CRO for different signal amplitudes and frequencies.
What is the CRO?
Cathode ray oscilloscope
What is CRO and AFO?

What is deflecting magnet?
Magnetic deflection sensitivity of a cathode ray oscilloscope (CRO) is defined as the amount of deflection of electron spot produced when a magnetic flux density of 1 Wb/m2 is applied. SM = (e / m )1\2 x 1\ (2V0) 1\2 x l x L
