The correct Answer is:
To solve the question, we need to identify the device that emits radiation in the microwave region. Let's break down the solution step by step: ### Step 1: Understand the Wavelengths of Different Regions - The electromagnetic spectrum is divided into various regions based on wavelength. The microwave region typically has wavelengths ranging from 30 cm (0.3 m) to 1 mm (0.001 m). ### Step 2: Identify the Device Related to Microwave Emission - The question asks for a device that emits radiation specifically in the microwave region. ### Step 3: Analyze the Options - We need to consider common devices that emit radiation: - **Laser**: Emits light in the visible spectrum (400 nm to 700 nm). - **Microwave Oven**: Uses microwaves but is not typically referred to as a device that emits radiation in the scientific sense. - **Masers**: This is a device that amplifies microwaves through stimulated emission of radiation, similar to how lasers work for visible light. ### Step 4: Conclusion - Since the question specifically refers to emitted radiation in the microwave region, the correct term for the device is **maser**, which stands for Microwave Amplification by Stimulated Emission of Radiation. ### Final Answer The device is termed as **maser**. ---
