How is the electron beam detected?

By deflecting the beam of electrons with an electric field.

By deflecting the beam of electrons with a magnetic field.

Which of the following components are essential for the operation of an old Cathode Ray Tube (CRT) television?

Electron Gun, Magnetic Coil, Phosphor Screen

LED Panel, Microprocessor, Speaker

Plasma Display, Optical Fiber, Power Inverter

Liquid Crystal Display, Backlight, Touch Sensor

What is the primary role of the electron gun in a CRT television?

To generate and direct a beam of electrons towards the screen.

To produce sound for the TV speakers.

To control the overall power supply to the TV.

To receive and decode incoming television signals.

What is the immediate effect when electrons from the electron gun strike the phosphors on the screen?

The phosphors emit light, creating visible points of an image.

The phosphors absorb the electrons and become electrically charged.

The phosphors generate heat, warming the screen.

The phosphors change their chemical composition.

How do magnetic coils contribute to displaying a moving picture on a CRT TV screen?

They rapidly deflect the electron beam to scan and draw the image.

They regulate the brightness of the screen.

They convert electrical energy into sound.

They filter out unwanted static from the signal.

Where did Wilhelm Conrad Röntgen make his discovery?

Institute for Physical Sciences in Munich

What was the initial observation that led to Röntgen's discovery when the induction current was switched on?

Several crystals on the table began to fluoresce.

The vacuum tube emitted a bright red light.

A photographic plate developed an image.

The room became completely dark.

What did Röntgen replace the screen with to capture the first images of internal structures, like a hand?

A different type of vacuum tube

Why do bones appear clearly visible in an X-ray image, while soft tissues appear shadowy?

Bones contain calcium, a denser material that stops some X-rays.

Bones are transparent to X-rays.

Soft tissues absorb all X-rays.

Soft tissues are too thin to be detected by X-rays.
