Answer the following questions as part of your laboratory report. Short answers are sufficient.
1. The voltage sensitivity of a set of deflection plates is defined as the deflection divided by the deflecting voltage. What is the voltage sensitivity of the vertical plates? How does it vary with the accelerating voltage?
2. Would you expect the voltage sensitivities of the horizontal and vertical plates to be the same or different? Why?
3. What is the speed of the electrons in the beam when the
accelerating voltage
? How much time is required for an electron
to reach the screen from the end of the electron gun?
4. Why are the deflection plates flared instead of having a uniform spacing?
