Understand the Problem
The question consists of several inquiries related to physical concepts such as dispersion, types of vision problems, and instruments used in measurements. It covers topics in optics, electronics, and the use of microwaves.
Answer
Improperly formatted question in input.
- Dispersion is the splitting of white light into its component colors. Violet is more dispersed.
- Myopia, or nearsightedness, is corrected with diverging lenses.
- Hypermetropia, or farsightedness, is corrected with converging lenses.
- An ammeter measures current in series; a voltmeter measures voltage in parallel.
- Convert a galvanometer to an ammeter by adding a low resistance in parallel.
- Principle of moving coil galvanometer involves torque on a current-carrying coil.
- Infrared rays are used in remote controls and thermal imaging.
- Microwaves are used in radars for their ability to penetrate clouds and rain.
- Applications of microwaves include cooking, communications, and radar.
- Microwaves are produced using magnetrons or klystrons.

More Information
Dispersion causes rainbows as light splits into a spectrum. Corrective lenses adjust focal points in vision defects. Microwaves interact with water molecules for cooking, and their wavelength is suitable for radar signal clarity.
Tips
Common errors include confusing ammeter and voltmeter connections, and misidentifying light spectrum nuances.
