Electron Diffraction Tube Quiz

What is the primary purpose of the electron diffraction tube?

• To create a magnetic field

• To generate electricity

• To demonstrate the wave behavior of electrons

• To measure the speed of electrons

What is the main safety concern when handling the electron diffraction tube?

• Short-circuiting the power supply

• Exposing the anode

• Breaking the evacuated bulb

• Overheating the filament

Why is the electron diffraction tube considered safe to use?

• It includes a high-value resistor limiting current

• It has a low voltage supply

• It is operated in a vacuum

• It is made of non-conductive materials

How does increasing the voltage affect the diffraction pattern?

• The rings become larger

• The pattern disappears

• The rings become closer together

• The pattern becomes more dispersed

What demonstrates that the diffraction pattern is produced by electrons and not light?

• The pattern disappears in the dark

• The pattern changes color

• The pattern is deflected by a magnet

• The pattern is visible only under UV light
