Cathode Ray Tube and Magnetic Field Interaction Quiz

What is the primary function of the slit in the cathode ray tube?

• To direct a focused beam of cathode rays

• To change the color of the fluorescent screen

• To allow air to enter the tube

• To prevent the tube from overheating

Why does the fluorescent screen in the cathode ray tube glow green?

• It is painted with a green phosphor

• It is hit by energetic electrons

• It is exposed to sunlight

What is the main advantage of using a Tesla coil with the cathode ray tube?

• It provides high voltage with high amperage

• It is a compact and portable power source

• It can change the color of the cathode ray beam

• It offers high voltage with low amperage, making it safe

What happens to the cathode ray beam when a magnet is brought near it?

• The beam changes color

• The beam disappears

• The beam bends and changes direction

• The beam becomes brighter

What property of the cathode ray particles makes them susceptible to a magnetic field?
