In CRO the time base circuit is connected to:
Correct answer: C. Horizontal plates
- A. Vertical plates
- B. Electron gun
- C. Horizontal plates
- D. Fluorescent screen
Explanation
The time base circuit in a CRO is connected to the horizontal plates. These plates control the horizontal deflection of the electron beam, determining the time scale or horizontal position of the displayed waveform. The time base circuit generates a time-varying voltage or current that controls the deflection of the beam across the screen.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
