Detailed Solution
Download Solution PDFThe correct answer is option 4.
The lamps used in searchlights are typically high-intensity lamps that can produce a focused and powerful beam of light over long distances. Among the following options:
- Neon lamps and fluorescent lamps are not typically used in searchlights because they do not produce the intense, focused beam required for such applications.
- Sodium vapor lamps are used in outdoor lighting but are not commonly employed in searchlights due to limitations in achieving the required intensity and focus.
- Arc lamps are commonly used in searchlights. These lamps generate light by creating an electric arc between two electrodes, producing a bright and concentrated light beam. Arc lamps are well-suited for applications where a powerful and directed light source is needed, such as in searchlights.
