Describe the components that make up the electron gun in a cathode-ray tube. 2. Describe the voltage waveform that produces a linear time scale when applied to the horizontal plates of a cathode-ray tube. 3. When the electron beam strikes the fluorescent screen, the phosphor glow that results has persistence. Approximately how long does the glow persist? 4. A function generator outputs a sine wave of f= 200 Hz. It is input to an oscilloscope set at 1 ms/DIV. How many complete cycles of the sine wave are displayed on the oscilloscope? (Hint-The period of the sine wave T is related to the frequency f of the wave by T = 1/f, and there are 10 divisions on the time display of the oscilloscope.)

2. During the experiment, the lights will be turned down. You will observe the electron beam as a purple green glow. This is caused when a small fraction of the electrons strike some of the very low density of mercury atoms in the residual gas of the partial vacuum. The beam electron knocks one of the atomic electrons into a higher energy orbit momentarily. When it comes back down to its ground state, the colored light is emitted. Why does the beam still seem to go in a circle, if the light only comes when an electron collides with an atom and hence is scattered off in some random direction?
The effective bandwidth of Hollow cathode lamp emission lines is smaller than that absorption lines by atoms in flame because a. In the flame, molecules move faster producing a wider bandwidth. b. The pressure is low in the HC lamp as a result more natural uncertainty broadening. c. In the HC lamp, the temperature is low so that the Doppler Effect is high causing more broadening. d. In flame, the gas temperature is high so that the collision is higher and resulting more broadening.
